Referencing sources

Tools and resources, a quick guide to working with sources.

Working with sources is an important skill that you’ll need throughout your academic career.

It includes knowing how to find relevant sources, assessing their authority and credibility, and understanding how to integrate sources into your work with proper referencing.

This quick guide will help you get started!

Finding relevant sources

Sources commonly used in academic writing include academic journals, scholarly books, websites, newspapers, and encyclopedias. There are three main places to look for such sources:

• Research databases: Databases can be general or subject-specific. To get started, check out this list of databases by academic discipline . Another good starting point is Google Scholar .
• Your institution’s library: Use your library’s database to narrow down your search using keywords to find relevant articles, books, and newspapers matching your topic.
• Other online resources: Consult popular online sources like websites, blogs, or Wikipedia to find background information. Be sure to carefully evaluate the credibility of those online sources.

When using academic databases or search engines, you can use Boolean operators to refine your results.

Get started

In academic writing, your sources should be credible, up to date, and relevant to your research topic. Useful approaches to evaluating sources include the CRAAP test and lateral reading.

CRAAP is an abbreviation that reminds you of a set of questions to ask yourself when evaluating information.

• Currency: Does the source reflect recent research?
• Relevance: Is the source related to your research topic?
• Authority: Is it a respected publication? Is the author an expert in their field?
• Accuracy: Does the source support its arguments and conclusions with evidence?
• Purpose: What is the author’s intention?

Lateral reading

Lateral reading means comparing your source to other sources. This allows you to:

• Verify evidence
• Contextualize information
• Find potential weaknesses

If a source is using methods or drawing conclusions that are incompatible with other research in its field, it may not be reliable.

Integrating sources into your work

Once you have found information that you want to include in your paper, signal phrases can help you to introduce it. Here are a few examples:

Following the signal phrase, you can choose to quote, paraphrase or summarize the source.

• Quoting : This means including the exact words of another source in your paper. The quoted text must be enclosed in quotation marks or (for longer quotes) presented as a block quote . Quote a source when the meaning is difficult to convey in different words or when you want to analyze the language itself.
• Paraphrasing: This means putting another person’s ideas into your own words. It allows you to integrate sources more smoothly into your text, maintaining a consistent voice. It also shows that you have understood the meaning of the source.
• Summarizing : This means giving an overview of the essential points of a source. Summaries should be much shorter than the original text. You should describe the key points in your own words and not quote from the original text.

Whenever you quote, paraphrase, or summarize a source, you must include a citation crediting the original author.

Referencing your sources is important because it:

• Allows you to avoid plagiarism
• Establishes the credentials of your sources
• Backs up your arguments with evidence
• Allows your reader to verify the legitimacy of your conclusions

The most common citation styles in the UK are APA, MLA, Harvard, Vancouver, MHRA, and Oscola. Each citation style has specific rules for formatting citations.

Scribbr’s free Reference Generator can generate perfect references and in-text citations in both APA and MLA styles. More citation styles will be available soon!

Being responsible while researching

When you’re writing a research paper or creating a research project, you will probably use another individual’s work to help develop your own assignment. A good researcher or scholar uses another individual’s work in a responsible way. This involves indicating that the work of other individuals is included in your project (i.e., citing), which is one way to prevent plagiarism.

Plagiarism? What is it?

The word plagiarism is derived from the Latin word, plagiare , which means “to kidnap.” The term has evolved over the years to now mean the act of taking another individual’s work and using it as your own, without acknowledging the original author (American Psychological Association, 2020 p. 21). Plagiarism can be illegal and there can be serious ramifications for plagiarizing someone else’s work. Thankfully, plagiarism can be prevented. One way it can be prevented is by including citations and references in your research project. Want to make them quickly and easily? Try the Citation Machine citation generator, which is found on our homepage.

All about citations & references

Citations and references should be included anytime you use another individual’s work in your own assignment. When including a quote, paraphrased information, images, or any other piece of information from another’s work, you need to show where you found it by including a citation and a reference. This guide explains how to make them.

APA style citations are added in the body of a research paper or project and references are added to the last page.

Citations , which are called in-text citations, are included when you’re adding information from another individual’s work into your own project. When you add text word-for-word from another source into your project, or take information from another source and place it in your own words and writing style (known as paraphrasing), you create an in-text citation. These citations are short in length and are placed in the main part of your project, directly after the borrowed information.

References are found at the end of your research project, usually on the last page. Included on this reference list page is the full information for any in-text citations found in the body of the project. These references are listed in alphabetical order by the author's last name.

An APA in-text citation includes only three items: the last name(s) of the author(s), the year the source was published, and sometimes the page or location of the information. References include more information such as the name of the author(s), the year the source was published, the full title of the source, and the URL or page range.

Why is it important to include citations & references

Including APA citations and references in your research projects is a very important component of the research process. When you include citations, you’re being a responsible researcher. You’re showing readers that you were able to find valuable, high-quality information from other sources, place them into your project where appropriate, all while acknowledging the original authors and their work.

Common ways students and scholars accidentally plagiarize

Believe it or not, there are instances when you could attempt to include in-text and full references in the appropriate places, but still accidentally plagiarize. Here are some common mistakes to be aware of:

Mistake #1 - Misquoting sources: If you plan to use a direct quote, make sure you copy it exactly as is. Sure, you can use part of the full quote or sentence, but if you decide to put quotation marks around any words, those words should match exactly what was found in the original source. Here’s a line from The Little Prince , by Antoine de Saint-Exupéry:

“Grown-ups never understand anything by themselves, and it is tiresome for children to be always and forever explaining things to them.”

Here’s an acceptable option:

“Grown-ups never understand anything by themselves,” stated de Saint-Exupéry (1943, p. 3).

Here’s a misquote:

“Grown-ups barely ever understand anything by themselves,” stated de Saint-Exupéry (1943, p. 3).

Notice the slight change in the words. The incorrect phrasing is an instance of accidental plagiarism.

Mistake #2 - Problems with paraphrasing: When we paraphrase, we restate information using our own words and writing style. It’s not acceptable to substitute words from the original source with synonyms.

Let’s use the same sentence from The Little Prince .

A correct paraphrase could be:

de Saint-Exupéry (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything. It’s too bad adults are unable to comprehend anything on their own (p. 3).

An incorrect paraphrase would be:

de Saint-Exupéry (1943) shares that adults never understand anything by themselves, and it is exhausting for kids to be always and forever clarifying things to them (p.3).

Notice how close the incorrect paraphrase is from the original. This is an instance of accidental plagiarism.

Make sure you quote and paraphrase properly in order to prevent accidental plagiarism.

If you’re having a difficult time paraphrasing properly, it is acceptable to paraphrase part of the text AND use a direct quote. Here’s an example:

de Saint-Exupery (1943) shares various ways adults frustrate children. One of the biggest being that kids have to explain everything, and “it is tiresome for children to be always and forever explaining things to them” (p. 3).

Information About APA

Who created it.

The American Psychological Association is an organization created for individuals in the psychology field. With close to 121,000 members, they provide educational opportunities, funding, guidance, and research information for everything psychology-related. They also have numerous high-quality databases, peer-reviewed journals, and books that revolve around mental health.

The American Psychological Association is also credited with creating their own specific citation and reference style. Today, this format is used by individuals not only in the psychology field, but many other subject areas as well. Education, economics, business, and social sciences also use APA style quite frequently. Click here for more information . This guide covers general information about the style, but is not affiliated with the American Psychological Association.

Why was this style created?

This format was first developed in 1929 to form a standardized way for researchers in science fields to document their sources. Prior to the inception of these standards and guidelines, individuals were recognizing the work of other authors by including bits and pieces of information in random order. There wasn’t a set way to format citations and references. You can probably imagine how difficult it was to understand the sources that were used for research projects!

Having a standard format for citing sources allows readers to glance at a citation or APA reference and easily locate the title, author, year published, and other critical pieces of information needed to understand a source.

The evolution of this style

The guide below is based on APA style 7th edition, which was released in 2020. In previous versions of APA format, researchers and scholars were required to include the publisher location for books and the date that an electronic resource was accessed. Both are no longer required to be included.

Details on the differences between the 6th and 7th editions is addressed later in this guide.

Citations & References

The appearance of citations & references.

The format for references varies, but most use this general format:

%%Author’s Last name, First initial. (Date published). Title . URL

Researchers and scholars must look up the proper format for the source that they’re attempting to cite. Books have a certain format, websites have a different format, periodicals have a different format, and so on. Scroll down to find the proper format for the source you’re citing or referencing.

If you would like help citing your sources, CitationMachine.com has a citation generator that will help make the APA citation process much easier for you. To start, simply click on the source type you're citing:

• Journal articles

In-text citations

An APA in-text citation is included in research projects in three instances: When using a direct quote, paraphrasing information, or simply referring to a piece of information from another source.

Quite often, researchers and scholars use a small amount of text, word for word, from another source and include it in their own research projects. This is done for many reasons. Sometimes, another author’s words are so eloquently written that there isn’t a better way to rephrase it yourself. Other times, the author’s words can help prove a point or establish an understanding for something in your research project. When using another author’s exact words in your research project, include an APA in-text citation directly following it.

In addition to using the exact words from another source and placing them into your project, these citations are also added anytime you paraphrase information. Paraphrasing is when you take information from another source and rephrase it, in your own words.

When simply referring to another piece of information from another source, also include a citation directly following it.

Citations in the text are found near a direct quote, paraphrased information, or next to a mention of another source. To see examples of some narrative/ parenthetical citations in action, look at the image above, under “All About Citations & References.”

Note: *Only include the page or paragraph number when using a direct quote or paraphrase. Page numbers have a p. before the number, pp. before the page range, and para. before the paragraph number. This information is included to help the reader locate the exact portion of text themselves. It is unnecessary to include this information when you’re simply referring to another source.

Examples of APA in-text citations:

“Well, you’re about to enter the land of the free and the brave. And I don’t know how you got that stamp on your passport. The priest must know someone” (Tóibín, 2009, p. 52).

Student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers (Kent & Giles, 2017, p. 12).

If including the author’s name in the sentence, place the year in the parentheses directly next to his or her name. Add the page number at the end, unless it’s a source without any pages or paragraph numbers (See Section 8.10 of the Publication manual for more details).

In-text citation APA example:

According to a study done by Kent and Giles (2017), student teachers who use technology in their lessons tend to continue using technology tools throughout their teaching careers.

The full references, or citations, for these sources can be found on the last part of a research project, titled the “References.”

Here’s how to create in-text citations for specific amounts of authors:

APA citation with no author

When the source lacks an author’s name, place the title, year, and page number (if available) in the text. The title should be in italics if it sits alone (such as a movie, brochure, or report). If the source is part of a whole (as many web pages and articles are), place the title in quotation marks without italics (See Section 8.14 of the Publication manual ).

Structure of an APA format citation in the text narratively, with the author's name missing:

Title of Source (Year) or “Title of Source” (Year)

Structure of an APA style format citation, in parentheses at the end of the sentence, with the author’s name missing: (Title of Source, Year) or (“Title of Source,” Year)

Structure for one author

In the text, narratively: Last name of Author (Year)...(page number).

In parentheses, at the end of the sentence: (Last name of Author, Year, page number).

Structure for two authors

Place the authors in the order they appear on the source. Only use the ampersand in the parenthetical citations (see Section 8.17 of the Publication manual ). Use ‘and’ to separate the author names if they’re in the text of the sentence.

In the text, narratively: Last name of Author 1 and Last name of Author 2 (Year)....(page number).

In parentheses, at the end of the sentence: (Last name of Author 1 & Last name of Author 2, Year, page number).

Structure for three or more authors

Only include the first listed author’s name in the first and any subsequent citations. Follow it with et al.

(Last name Author 1 et al., Year, page number)

(Agbayani et al., 2020, p. 99)

Last name of Author 1 et al. (Year)...(page).

Agbayani et al. (2020)...(p. 99)

One author, multiple works, same year

What do you do when you want to cite multiple works by an author, and the sources all written in the same year?

Include the letters ‘a’ ‘b’ ‘c’ and so on after the year in the citation.

(Jackson, 2013a)

Jackson (2013a)

Writers can even lump dates together.

Example: Jackson often studied mammals while in Africa (2013a, 2013b).

On the APA reference page, include the same letters in the full references.

Groups and organizations

Write out the full name of the group or organization in the first citation and place the abbreviation next to it in brackets. If the group or organization is cited again, only include the abbreviation. If it doesn’t have an abbreviation associated with it, write out the entire organization’s name each and every time (see Section 8.21 of the Publication manual ).

First APA citation for an organization with an abbreviation: (World Health Organization [WHO], Year)

World Health Organization (WHO, Year)

Notice in the example directly above, the name of the organization is written out in full in the text of the sentence, and the abbreviation is placed in parentheses next to it.

Subsequent APA citations in the text for an organization with an abbreviation: (WHO, Year) OR WHO (Year)

All citations in the text for an organization without an abbreviation: (Citation Machine, Year) or Citation Machine (Year)

One in-text citation, multiple works

Sometimes you’ll need to cite more than one work within an in-text citation. Follow the same format (author, year) format but place semicolons between works (p. 263).

(Obama, 2016; Monroe et al., 1820; Hoover & Coolidge, 1928)

Reference list citation components

References display the full information for all the citations found in the body of a research project.

Some things to keep in mind when it comes to the references:

• All references sit together on their own page, which is usually the last page(s) of a paper.
• Title the page ‘References’
• Place ‘References’ in the center of the page and bold it. Keep the title in the same font and size as the references. Do not italicize, underline, place the title in quotation marks, or increase the font size.
• The entire page is double spaced.
• All references are listed in alphabetical order by the first word in the reference, which is usually the author’s last name. If the source lacks an author, alphabetize the source by the title (ignore A, An, or The)
• All references have a hanging indent, meaning that the second line of text is indented in half an inch. See examples throughout this guide.
• Remember, each and every citation in the text of the paper MUST have a full reference displayed in the reference list. The citations in the text provide the reader with a quick glimpse about the sources used, but the references in the reference list provide the reader with all the information needed to seek out the source themselves.

Learn more about each component of the reference citation and how to format it in the sections that follow. See an APA sample paper reference list at the end of this entire section.

Author’s names

The names of authors are written in reverse order. Include the initials for the first and middle names. End this information with a period (see Section 9.8 of the Publication manual ).

Format: Last name, F. M.

• Angelou, M.
• Doyle, A. C.

Two or more authors

When two or more authors work together on a source, write them in the order in which they appear on the source. You can name up to 20 authors in the reference. For sources with 2 to 20 authors, place an ampersand (&) before the final author. Use this format:

Last name, F. M., & Last name, F. M.

Last name, F. M., Last name, F. M., Last name, F. M., Last name, F. M., & Last name, F. M.

Kent, A. G., Giles, R. M., Thorpe, A., Lukes, R., Bever, D. J., & He, Y.

If there are 21 or more authors listed on a source, only include the first 19 authors, add three ellipses, and then add the last author’s name.

Roberts, A., Johnson, M. C., Klein, J., Cheng, E. V., Sherman, A., Levin, K. K. , ...Lopez, G. S.

If you plan on using a free APA citation tool, like the one at CitationMachine.com, the names of the authors will format properly for you.

###No authors

If the source lacks an author, place the title in the first position in the reference (Section 9.12 of the Publication manual ). When the source’s title begins with a number (Such as 101 Dalmatians ), place the reference alphabetically as if the number was spelled out. 101 Dalmatians would be placed in the spot where ‘One hundred’ would go, but keep the numbers in their place.

Additionally, if the title begins with the words ‘A’, ‘An,’ or ‘The,’ ignore these words and place the title alphabetically according to the next word.

See the “Titles” section below for more information on formatting the title of sources.

###Corporate/Organization authors

On an APA reference page, corporate authors are always written out in full. In the text of your paper, you may have some abbreviations (such as UN for United Nations), but in the full references, always include the full names of the corporation or organization (following Section 9.11 of the official Publication manual ).

%%United Nations. (2019). Libya: $202 million needed to bring life-saving aid to half a million people hit by humanitarian crisis. https://news.un.org/en/story/2019/02/1031981

Publication date & retrieval date

Directly after the author’s name is the date the source was published. Include the full date for newspapers and magazine articles, and only the year for journals and all other sources. If no date is found on the source, include the initials, n.d. for “no date.”

%% Narducci, M. (2017, May 19). City renames part of 11th Street Ed Snider Way to honor Flyers founder. The Philadelphia Inquirer . http://www.philly.com/

If using our APA Citation Machine, our citation generator will add the correct format for you automatically.

Giving a retrieval date is not needed unless the online content is likely to be frequently updated and changed (e.g., encyclopedia article, dictionary entry, Twitter profile, etc.).

%%Citation Machine [@CiteMachine]. (n.d.). Tweets [Twitter profile]. Twitter. Retrieved October 10, 2019, from https://twitter.com/CiteMachine

When writing out titles for books, articles, chapters, or other non-periodical sources, only capitalize the first word of the title and the first word of the subtitle. Names of people, places, organizations, and other proper nouns also have the first letter capitalized. For books and reports, italicize the title in the APA citation.

Strange case of Dr. Jekyll and Mr. Hyde.

Roots: The saga of an American family.

For articles and chapters in APA referencing, do not italicize the title.

Wake up the nation: Public libraries, policy making, and political discourse.

For newspapers, magazines, journals, newsletters, and other periodicals, capitalize the first letter in each word and italicize the title.

The Seattle Times.

A common question is whether to underline your title or place it in italics or quotation marks in the reference list. Here’s a good general rule: When a source sits alone and is not part of a larger whole, place the title in italics. If the source does not sit alone and is part of a larger whole, do not place it in italics.

Books, movies, journals, and television shows are placed in italics since they stand alone. Songs on an album, episodes of television shows, chapters in books, and articles in journals are not placed in italics since they are smaller pieces of larger wholes.

The Citation Machine citation generator will format the title in your citations automatically.

Additional information about the title

If you feel it would be helpful to include additional information about the source type, include a descriptive noun or two in brackets immediately following the title. Capitalize the first letter.

%%Kennedy, K., & Molen, G. R. (Producers), & Spielberg, S. (Director). (1993). Jurassic Park [Film]. USA: Universal.

Besides [Film], other common notations include:

• [Audio podcast]
• [Letter to the editor]
• [Television series episode]
• [Facebook page]
• [Blog post]
• [Lecture notes]
• [PowerPoint presentation]
• [Video file]

If you are using Citation Machine citing tools, additional information about the title is automatically added for you.

Publisher information

For books and reports, include the publisher name but not the location (see Section 9.29 of the Publication manual ). Older editions of the style required the city, state and/or country, but this hasn't been the case since the 7th edition was released.

It is not necessary to include the entire name of the publisher. It is acceptable to use a brief, intelligible form. However, if Books or Press are part of the publisher’s names, keep these words in the reference. Other common terms, such as Inc., Co., Publishers, and others can be omitted.

For newspapers, journals, magazines, and other periodicals, include the volume and issue number after the title. The volume number is listed first, by itself, in italics. The issue number is in parentheses immediately after it, not italicized. There is no space after the closing parenthesis and before the volume number.

%%Giannoukos, G., Besas, G., Hictour, V., & Georgas, T. (2016). A study on the role of computers in adult education. Educational Research and Reviews , 11 (9), 907-923. https://doi.org/10.5897/ERR2016.2688

After including the publisher information, end this section with a period.

Perseus Books.

Electronic source information:

For online sources, the URL or DOI (Direct Object Identifier) are included at the end of an APA citation.

DOI numbers are often created by publishers for journal articles and other periodical sources. They were created in response to the problem of broken or outdated links and URLs. When a journal article is assigned a DOI number, it is static and will never change. Because of its permanent characteristic, DOIs are the preferred type of electronic information to include in APA citations. When a DOI number is not available, include the source’s URL (see Section 9.34 in the Publication manual ).

For DOIs, include the number in this format:

http://doi.org/xxxx

For URLs, type them in this format:

http:// or https://

Other information about electronic sources:

• If the URL is longer than a line, break it up before a punctuation mark.
• Do not place a period at the end of the citation/URL.
• It is unnecessary to include retrieval dates, unless the source changes often over time (like in a Wikipedia article).
• It is not necessary to include the names of databases

If using the Citation Machine APA citation website autocite features, the online publication information will be automatically replaced by the DOI. The Citation Machine APA template will properly cite your online sources for you.

Make sure you run your completed paper through the Citation Machine Plus smart proofreader, which scans for grammar, spelling, and plagiarism. Whether it’s an adjective , verb , or pronoun out-of-place, our technology helps edits your paper for you!

Annotated bibliographies:

An APA annotated bibliography is a full bibliography that includes a small note for each reference citation. Each note should be short (1-2 paragraphs) and contain a summary or your evaluation about each source. When creating your citations on CitationMachine.net, there is a field at the bottom of each form to add your own annotations.

Follow the publication manual guidelines on paper format and writing style. Let your instructor guide other details about your annotations. Still confused? Read our guide on annotated bibliographies .

These types of projects look different depending on the style you’re using. Use the link at the top of the page to access resources related to the Modern Language Association’s style. Here’s information related to Chicago citation style .

Page formatting

Need help with the design and formatting of your paper? Look no further! This section provides the ins and outs of properly displaying the information in your APA essay.

• Times New Roman, 12-point size.
• Calibri, Arial, or Georgia, 11-point size
• Lucida, Sans Unicode, or Computer Modern, 10-point size
• Indents = Every paragraph should start with an indent.
• Margins = 1 inch around the entire document
• Spacing = Double space everything!

Arrange your pages in this order:

• Page 1 - APA Title Page (see below for information on the title page)
• Page 2 - Abstract (If your professor requests one)
• Page 3 - First page of text
• References begin on their own page. Include the list of references on the page after the text.
• Tables and figures

Keep in mind that the order above is the recommendation for papers being submitted for peer review. If you’re writing an APA style paper for a class, your professor may be more lenient about the requirements. Also, if you’re submitting your paper for a specific journal, check the requirements on the journal’s website. Each journal has different rules and procedures.

Just a little nudge to remind you about the Citation Machine Plus smart proofreader. Whether it’s a conjunction or interjection out of place, a misspelled word, or an out of place citation, we’ll offer suggestions for improvement! Don’t forget to check out our APA citation maker while you’re at it!

Running heads

In older editions of APA, running heads were required for all papers. Since the 7th edition, that’s changed.

• Student paper: No running head
• Professional paper: Include a running head

The running head displays the title of the paper and the page number on all pages of the paper. This header is found on every page of a professional paper (not a student paper), even on the title page (sometimes called an APA cover page) and reference list (taken from Section 2.8 of the Publication manual ).

It's displayed all in capital letters at the top of the page. Across from the running head, along the right margin, is the page number.

• Use the header feature in your word processor. Both Google Docs and Word have these features available.
• Use one for the recommended fonts mentioned under "Page formatting."

Title pages

A title page, sometimes called an APA cover page, graces the cover of an essay or paper. An APA title page should follow rules from Section 2.3 of the official Publication manual and include:

• Page number, which is page 1
• Use title case and bold font
• The title should be under 12 words in length
• The title should be a direct explanation of the focus of the paper. Do not include any unnecessary descriptors such as “An Analysis of…” or “A Study of…”
• Exclude any labels such as Mr., Ms., Dr, PhD...
• Name of the school or institution
• Course number and/or class name
• Name of your instructor, including their preferred honorifics (e.g., PhD, Dr., etc.)
• Paper’s due date
• If this is a professional paper, also include a running head. If this is a student paper, do not include one.

Follow the directions for the running head and page number in the section above. Below the running head, a few lines beneath, and centered in the middle of the page, should be the title. The next line below is the author’s name(s), followed by the name of the school or institution, the class or course name, your instructor’s name, and the paper’s due date.

All components on this page should be written in the same font and size as the rest of your paper. Double space the title, names, name of school or institution, and all other information on the page (except for the running head and page number).

Example - Student Title Page APA:

Example - Professional Title Page APA:

If you’re submitting your paper to a journal for publication, check the journal’s website for exact requirements. Each journal is different and some may request a different type of APA format cover page.

An abstract briefly but thoroughly summarizes dissertation contents. It’s found in the beginning of a professional paper, right after the title page. Abstracts are meant to help readers determine whether to continue reading the entire document. With that in mind, try to craft the lead sentence to entice the reader to continue reading.

Here are a few tips:

• Be factual and keep your opinions out. An abstract should accurately reflect the paper or dissertation and should not involve information or commentary not in the thesis.
• Communicate your main thesis. What was the examined problem or hypothesis? A reader should know this from reading your abstract.
• Keep it brief. Stick to the main points and don’t add unnecessary words or facts. It should not exceed 250 words.
• Consider your paper’s purpose. It’s important to cater your abstract to your paper type and think about what information the target audience for that paper type would want. For example, an empirical article may mention methodology or participant description. A quantitative or qualitative meta-analysis would mention the different variables considered and how information was synthesized.
• Use verbs over noun equivalents, and active voice. Example: “There was research into…” becomes “We researched…”

Formatting guidelines:

• The abstract goes after the title page.
• It should have the same font (size and type) as the rest of the paper.
• It should stick to one page.
• Double-space all page text.
• Center and bold the word “Abstract” at the top of the paper.
• Don’t indent the first line of the abstract body. The body should also be in plain text.
• For the keywords, place it on the line after the abstract and indent the first line (but not subsequent lines). The word “Keywords:” is capitalized, italicized, and followed by a colon. The actual keywords are sentence case and in plan font.
• List each keyword one after the other, and separate them by a comma.
• After the last keyword, no ending punctuation is needed.

Tables & Figures

If your paper includes a lot of numerical information or data, you may want to consider placing it into a table or a figure, rather than typing it all out. A visual figure or simple, organized table filled with numerical data is often easier for readers to digest and comprehend than tons of paragraphs filled with numbers. Chapter 7 of the Publication manual outlines formatting for tables and figures. Let's cover the basics below.

If you’d like to include a table or figure in your paper, here are a few key pieces of information to keep in mind:

• At the end of the paper after the APA reference page
• In the text after it is first mentioned
• The table first mentioned in the text should be titled ‘Table 1.’ The next table mentioned in the text is ‘Table 2,’ and so on. For figures, it would be 'Figure 1,' 'Figure 2,' and so forth.

• Even though every table and figure is numbered, also create a title for each that describes the information it contains. Capitalize all important words in the title.
• For tables, do not use any vertical lines, only use horizontal to break up information and headings.
• Single spacing is acceptable to use in tables and figures. If you prefer double spacing your information, that is okay too.
• Do not include extra information or “fluff.” Keep it simple!
• Do not include the same exact information in the paper. Only include the complete information in one area—the table or the text.
• All tables and figures must be referenced in the text. It is unacceptable to throw a table or figure into the back of the paper without first providing a brief summary or explanation of its relevance.

Publication Manual 6th Edition vs 7th Edition

The 6th edition of the Publication Manual of the American Psychological Association was released in 2009. The current 7th edition came out in the fall of 2019 and was designed to be more student focused, provide more guidance on accessibility, and address changes that have developed over the last 10 years.

Below, we’ve listed what we feel are the most relevant changes related to APA format.

Journals and DOIs

DOI stands for “digital object identifier.” Many journal articles use and have a unique DOI that should be included in a full citation.

When including a DOI in a citation, format it as a URL. Do not label it “DOI.” Articles without DOIs from databases are treated as print works. For example:

6th edition:

%%Gänsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. doi: 10.1038/s41586-019-1789-8

7th edition:

%%Gänsicke, B. T., Schreiber, M. R., Toloza, O., Fusillo, N. P. G., Koester, D., & Manser, C. J. (2019). Accretion of a giant planet onto a white dwarf star. Nature, 576 (7785), 61–64. https://doi.org/10.1038/s41586-019-1789-8

Citing Books

There are few new guidelines when you are citing a book. First, the publisher location no longer needs to be indicated.

%%Zack, P. O. (2001). The shoals of time. Bloomington, IN: First Books Library.

%%Zack, P. O. (2001). The shoals of time. First Books Library.

Second, the format of an ebook (e.g., Kindle, etc.) no longer needs to be indicated.

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic [Kindle].

%%Niven, J. (2012). Ada Blackjack: A true story of survival in the Arctic .

Lastly, books from research databases without DOIs are treated the same as print works.

When using a URL in a citation, you no longer need to include the term “Retrieved from” before URLs (except with retrieval dates). The font should be blue and underlined, or black and not underlined.

6th Edition:

%%Flood, A. (2019, December 6). Britain has closed almost 800 libraries since 2010, figures show. The Guardian . Retrieved from https://www.theguardian.com/books/2019/dec/06/britain-has-closed-almost-800-libraries-since-2010-figures-show

7th Edition:

%%Flood, A. (2019, December 6). Britain has closed almost 800 libraries since 2010, figures show. The Guardian . https://www.theguardian.com/books/2019/dec/06/britain-has-closed-almost-800-libraries-since-2010-figures-show

Within a full APA citation, you may spell out up to 20 author names. For two to 20 authors, include an ampersand (&) before the name of the last author. For sources with 21 or more authors, structure it as follows:

Structure: First 19 authors’ names, . . . Last author’s name.

7th edition example: Washington, G., Adams, J., Jefferson, T., Madison, J., Monroe, J., Adams, J. Q., Jackson, A., Van Buren, M., Harrison, W. H., Tyler, J., Polk, J. K., Taylor, Z., Filmore, M., Pierce, F., Buchanan, J., Lincoln, A., Johnson, A., Grant, U. S., Hayes, R. B., Garfield, . . . Trump, D.

When creating an in-text citation for a source with 3 or more authors, use “et al.” after the first author’s name. This helps abbreviate the mention.

6th Edition: (Honda, Johnson, Prosser, Rossi, 2019)

7th Edition: (Honda et al., 2019)

Tables and Figures

Instead of having different formats for tables and figures, both use one standardized format. Now both tables and figures have a number, a title, name of the table/figure, and a note at the bottom.

Citation Generator

Welcome to a comprehensive guide on citing sources and formatting papers in the American Psychological Association style. Below are reference and in-text citation examples, directions on formatting your paper, and background information on the style.

What is APA?

APA stands for the American Psychological Association , which is an organization that focuses on psychology. They are responsible for creating this specific citation style. They are not associated with this guide, but all of the information here provides guidance to using their style and follows the Publication Manual of the American Psychological Association.

What is APA Citing?

APA style is used by many scholars and researchers in the behavioral and social sciences, not just psychology. There are other citation formats and styles such as MLA and Chicago citation style , but this one is most popular in the fields of science.

Following the same standard format for citations allows readers to understand the types of sources used in a project and also understand their components.

The information in this guide follows the 7th edition of the Publication Manual of the American Psychological Association . It outlines proper ways to organize and structure a research paper, explains grammar guidelines, and how to properly cite sources. This webpage was created solely by BibMe to help students and researchers focus on how to create APA citations.

The 7th edition of the Publication Manual was released in 2020. We address differences between the 6th and 7th editions at the end of this guide.

For more information, please consult the official Publication Manual .

We cite sources for many reasons. One reason is to give credit to the authors of the work you used to help you with your own research. When you use another person's information to help you with your project, it is important to acknowledge that individual or group. This is one way to prevent plagiarism. Another reason why we create citations is to provide a standard way for others to understand and possibly explore the sources we used. To learn more about citations, check out this page on crediting work . Also, read up on how to be careful of plagiarism .

What Does it Look Like?

There are two types of citations:

• In-text/Parenthetical citations: Those that are found in the body of a project are called in-text/parenthetical citations. They're added into a project when a direct quote or paraphrase has been added into your work. These citations only include the name(s) of the author(s), date, and page number(s), if applicable.
• References: Those that are found on the final part of a project are called references. They're are found in the reference list (sometimes called APA works cited by some teachers), which is at the end of the assignment. It includes the full information of all sources used in a project. These types of references show the author's name, date published, title, publisher, URL, and other key pieces of information.

Depending on the types of sources used for your project, the structure for each citation may look different. There is a certain format or structure for books, a different one for journal articles, a different one for websites, and so on. Scroll down to find the appropriate APA format structure for your sources.

Even though the structure varies across different sources, see below for a full explanation of in-text citations and reference citations.

Still wondering, "What is APA format?" To learn more about APA referencing, including access to the American Psychological Association\'s blog, formatting questions, & referencing explanations, click on this link for further reading on the style . To learn more about using the BibMe service (BibMe.com) to help build APA citation website references, see the section below titled, "Using the BibMe Online Writing Center to Create Citations for your Reference List or APA Bibliography."

Citing Basics

In-text citations overview.

When using a direct quote or paraphrasing information from a source, include an in-text or parenthetical citation into the body of your project, immediately following it.

An APA in-text citation may look similar to this:

Author's Last name (Year) states that "direct quote" or paraphrase (page number).

Parenthetical citations look like this:

"Direct quote" or paraphrase (Author's Last name, Year, Page number).

These types of APA citations always have the author and the date together.

Only direct quotes need a page number. For paraphrased information, it isn't necessary, but helpful for the reader.

See the section below titled, "In-Text or Parenthetical Citations," for a full explanation and instructions.

Full References Overview

Each source used in your project is listed as a full citation on the APA reference page, which is usually the last part of a project.

The structure for each citation is based on the type of source used. Scroll down to see APA format examples of some common source formats.

Most print and offline citations include the following pieces of information, commonly in this order:

Author's Last name, First initial. Middle initial. (Date published). Title of source . Publisher.

Most online citations include the following pieces of information, commonly in this order:

Author's Last name, First Initial. Middle initial. (Date published). Title of source . URL

To see how to format each section, scroll down to the appropriate areas of this guide. There is a section on authors, one on publication dates, another on titles, publishers, and on online information.

To determine the exact APA citation format for your full citations, scroll down to the section titled, "Common Examples."

For a detailed explanation on formatting your reference list, scroll down to the section titled, "Your Reference List."

Here's a quick snapshot of the basics:

All in-text citations included throughout the paper should have a corresponding full reference at the end of the project.

Full references go on their own page at the end of a project. Title the page "References"

References are listed in alphabetical order by the first word in the reference (usually the author's last name, sometimes the title).

• If the reference begins with the words A , An , or The , ignore them and alphabetize the reference by the word following it.

If you're looking for an easy way to create your references and citations, use BibMe's free APA citation machine, which automatically formats your sources quickly and easily.

Citation Components

How to structure authors.

Authors are displayed in reverse order: Last name, First initial. Middle initial. End this information with a period.

APA format example:

Kirschenbaum, M. A.

In an APA citation, include all authors shown on a source. If using the BibMe APA citation builder, click "Add another contributor" to add additional author names. Our free citation creator will format the authors in the order in which you add them.

Multiple authors, same last name:

If your reference list has multiple authors with the same last name and initials, include their first name in brackets.

Brooks, G. [Geraldine]. (2005). March . Viking.

Brooks, G. [Gwendolyn]. (1949). Annie Allen . Harper & Brothers.

When no author is listed, exclude the author information and start the citation with the title followed by the year in parentheses.

When citing an entire edited book in APA format, place the names of editors in the author position and follow it with Ed. or Eds. in parentheses. See below for examples of citing edited books in their entirety and also APA citation format for chapters in edited books.

Comparison chart:

Use this handy chart to determine how to format author names in citations and references.

How to Structure Publication Dates

General structure is:

• Year, Month Day
• Example: 1998, March 22

Place the date that the source was published in parentheses after the name of the author. In APA format for periodicals, include the month and day as well. If no date is available, place n.d. in parentheses, which stands for no date. For more details, see Section 9.14 of the Publication Manual .

How to Structure the Title

For book titles: Only capitalize the first letter of the first word in the title and the same for the subtitle. Capitalize the first letter for any proper nouns as well. Place this information in italics. End it with a period.

Gone with the wind.

For articles and chapter titles: Only capitalize the first letter of the first word in the title and the same for the subtitle. Capitalize the first letter for any proper nouns as well. Do not italicize the title or place it in quotation marks. End it with a period.

The correlation between school libraries and test scores: A complete overview.

For web pages on websites: Same as above. The web page title is italicized.

Simmons, B. (2015, January 9). The tale of two Flaccos . Grantland. http://grantland.com/the-triangle/the-tale-of-two-flaccos/

For magazine, journal, and newspaper titles: Each important word should start with a capital letter.

The Boston Globe

If you believe that it will help the reader to understand the type of source, such as a brochure, lecture notes, or an audio podcast, place a description in brackets directly after the title. Only capitalize the first letter.

New World Punx. (2014, February 15). A state of trance 650 [Audio file]. https://soundcloud.com/newworldpunx/asot650utrecht

How to Structure Publication Information

Publisher Location

In previous editions of the publication manual, books and sources that were not periodicals indicated the city and state of publication. However, in the 7th edition, the location of publication is no longer given except “for works associated with specific locations, such as conference presentations” (p. 297).

For conference presentations, give the city, state/province/territory, and country. If in the US, abbreviate the state name using the two-letter abbreviation. Place a colon after the location.

• Philadelphia, PA:
• Rotterdam, Netherlands:

Periodical Volume and Number

For journals, magazines, newspapers, and other periodicals, place the volume number after the title. Italicize this information. Place the issue number in parentheses and do not italicize it. Afterwards, include page numbers.

Journal of Education for Library and Information Science, 57 (1), 79-82.

If you're citing a newspaper article, include p. or pp. before the page numbers.

How to Structure the Publisher

The names of publishers are not necessary to include for newspapers, magazines, journals, and other periodicals.

For books and other sources: It is not necessary to type out the name of the publisher exactly as it is shown on the source. Use a brief, but understandable form of the publisher's name. Exclude the terms publishers, company, and incorporated. Include Books and Press if it is part of the publisher's name. End this information with a period (See Section 9.29 in the Publication manual for more details).

Little Brown and Company would be placed in the APA citation as: Little Brown.

Oxford University Press would be placed in the citation as: Oxford University Press.

How to Structure Online Sources

For sources found online:

• include the URL at the end of the citation
• do not place a period after the URL

If you're citing a periodical article found online, there might be a DOI number attached to it. This stands for Direct Object Identifier. A DOI, or digital object identifier, is a unique string of numbers and letters assigned by a registration agency. The DOI is used to identify and provide a permanent link to its location on the Internet. The DOI is assigned when an article is published and made electronically. If your article does indeed have a DOI number, use this instead of the URL as the DOI number is static and never changes. If the source you're citing has a DOI number, after the publication information add a period and then http://dx.doi.org/10.xxxx/xxxxxx. The x's indicate where you should put the DOI number. Do not place a period after the DOI number. See sections 9.35-36 in the Publication manual for more details.

If you're using the automatic BibMe APA reference generator, you will see an area to type in the DOI number.

Lobo, F. (2017, February 23). Sony just launched the world's fastest SD card. http://mashable.com/2017/02/23/sony-sf-g-fastest-sd-card/?utm_cid=mash-prod-nav-sub-st#ErZKV8blqOqO

Chadwell, F.A., Fisher, D.M. (2016). Creating open textbooks: A unique partnership between Oregon State University libraries and press and Open Oregon State. Open Praxis, 8 (2), 123-130. http://dx.doi.org/10.5944/openpraxis.8.2.290

Citations and Examples

Citations for print books.

Finney, J. (1970). Time and again . Simon and Schuster.

Looking for an APA formatter? Don't forget that the BibMe APA citation generator creates citations quickly and easily.

Notes: When creating an APA book citation, keep these in mind:

• Capitalize the first letter of the first word of the title and any subtitles, as well as the first letter of any proper nouns.
• The full title of the book, including any subtitles, should be stated and italicized.

Citations for Edited Books

Most edited books state on the cover or title page that they are edited by an author or multiple authors. The format is the same as a print book, except the editor's name is in the author's position. Include a parentheses afterwards with the abbreviation (Ed.) for an edited book by one author or (Eds.) for an edited book with two or more authors.

Editor, F. M. (Ed.). (Year published). Title of edited book . Publisher.

Gupta, R. (Ed.). (2003). Remote sensing geology . Springer-Verlag.

Citations for Chapters in Edited Books

Some edited books contain chapters written by various authors. Use the format below to cite an author's individual chapter in an edited book.

Chapter author's Last name, F. M. (Year published). Title of chapter. In F. M. Last name of Editor (Ed.), Title of book (p. x or pp. x-x). Publisher.

Notice that for APA style, the title of the chapter is not italicized, while the title of the book is. In addition, the chapter author's name is reversed at the beginning of the reference, but the editor's name is written in standard order.

Longacre, W. A., & Ayres, J. E. (1968). Archeological lessons from an Apache wickiup. In S. R. Binford & L. R. Binford (Eds.), Archeology in cultural systems (pp. 151-160). https://books.google.com/books?id=vROM3JrrRa0C&lpg=PP1&dq=archeology&pg=PR9#v=onepage&q=archeology&f=false

In the above example, Longacre and Ayers are the authors of the individual chapter and Binford & Binford are the editors of the entire book.

Citing an E-book from an E-reader

E-book is short for "electronic book." It is a digital version of a book that can be read on a computer, e-reader (Kindle, Nook, etc.), or other electronic devices. Include the DOI or URL if one exists for the e-book.

Author's Last name, F. M. (Year published). Title of work . https://doi.org/10.xxxx/xxxxxx or URL

https://doi.org/10.xxxx/xxxxxx is used when a source has a DOI number. If the e-book you're citing has a DOI number, use it in the APA citation. DOIs are preferred over URLs.

How to cite in APA (an e-book example):

Eggers, D. (2008). The circle . https://www.amazon.com

Citing an E-book Found in a Database and Online

Use this format when citing an e-book that is either found on a website, or found on a subscription database. APA formatting for this is very similar to the structure of a print book. The only difference? Instead of the publisher information, include the DOI number or URL.

Author's Last name, F. M. (Year published). Title of work . https://doi.org/10.xxxx/xxxxxx OR URL

When citing an online book or e-book, keep in mind:

• A DOI (digital object identifier) is an assigned number that helps link content to its location on the Internet. It is therefore important, if one is provided, to use it when creating a citation. In place of the x's in the DOI format, place the 10 digit DOI number.
• Notice that for e-books, publication information is excluded from the citation.

Sayre, R. K., Devercelli, A. E., Neuman, M. J., & Wodon, Q. (2015). Investment in early childhood development: Review of the world bank's recent experience . https://doi.org/10.1596/978-1-4648-0403-8

Citations for Chapters in E-books

Need to cite a chapter in an e-book? No problem! Citing a chapter in an e-book is very similar to citing a chapter in a print book. Instead of including the publisher information, include a DOI number (if one is displayed) or the URL.

Chapter author's Last name, F. M. (Year published). Title of chapter. In F. M. Last name of Editor (Ed.), Title of book (p. x or pp. x-x). https://doi.org/10.xxxx/xxxxxx or URL

Epstein W. M. (1999). The ineffectiveness of psychotherapy. In C. Feltham (Ed.), Controversies in psychotherapy and counselling (pp. 65-73). https://doi.org/10.4135/9781446217801.n8

Citations for Websites

How to cite a web page on a website in APA:

Author's Last name, F. M. (Year, Month Day published). Title of article or page . Site Name. URL

APA website citation example:

Citing a web page with a group author:

Group Name. (Year, Month Date published). Title of wep page . Saite Name included if different from Group Name. URL

Centers for Disease Control and Prevention. (2020, February 3). Be prepared to stay safe and healthy in winter . https://www.cdc.gov/features/winterweather/index.html

National Park Service. (n.d.). Enchanting landscapes beneath the parks . https://www.nps.gov/subjects/caves/index.htm

Note: "n.d." stands for "no date" and is used when there is no publication date.

The above follows Section 10.16 of the Publication manual.

Citations for Journal Articles Found in Print

Today, most journal articles are found online, but you may be lucky enough to score a copy of a print version for your research project. If so, use the structure below for your reference:

Author's Last name, F. M. (Year published). Article title. Periodical Title, Volume (Issue), pp.-pp.

Notice that the article's title is only capitalized at the beginning. If there are any proper nouns or subtitles, capitalize the first letter for those words as well. The journal article's title and the volume number are both italicized. In addition, the title of the journal is in title case form (all important words are capitalized).

Nevin, A. (1990). The changing of teacher education special education. Teacher Education and Special Education: The Journal of the Teacher Education Division of the Council for Exceptional Children,13 (3-4), 147-148.

Citations for Journal Articles Found Online

Databases are a popular place to find high quality journal articles. These references are formatted the same way as the print versions, except the DOI or URL is included at the end. If the article has a corresponding DOI number, use it instead of the URL. No URL? Use the homepage of the journal's website for the URL. See Section 10.1 in the Publication manual for additional examples.

Author's Last name, F. M. (Year published). Title of article. Title of Journal, volume number (issue number), page range. https://doi.org/10.xxxx/xxxxxx OR URL

Spreer, P., & Rauschnabel, P. A. (2016). Selling with technology: Understanding the resistance to mobile sales assistant use in retailing. Journal of Personal Selling & Sales Management, 36 (3), 240-263. https://doi.org/10.1080/08853134.2016.1208100

Notes: When creating your online journal article citation, keep in mind:

• This citation style does NOT require you to include the date of access/retrieval date or database information for electronic sources.
• Use the URL of the journal homepage if there is no DOI assigned and the reference was retrieved online. * If the journal article has a DOI number assigned to it, include that number in the citation instead of a URL.

Citations for a Newspaper Article in Print

Similar to journal articles, most individuals use online newspaper articles for research projects. However, if you're able to get your hands on a print version, use this structure for your reference:

Author's Last name, F. M. (Year, Month Day of Publication). Article title. Newspaper Title, pp. xx-xx.

Rosenberg, G. (1997, March 31). Electronic discovery proves an effective legal weapon. The New York Times, p. D5.

Notes: When creating your newspaper citation, keep in mind:

• Begin page numbers with p. (for a single page) or pp. (for multiple pages).
• Even if the article appears on non-consecutive pages, include all page numbers, and use a comma to separate them. Example: pp. C2, C5, C7-C9.
• Include the full date of publication, not just the year like in most references.

Citations for Newspapers found Online

Use this structure when referencing a newspaper article found on a website or database:

Author's Last name, F. M. (Year, Month Day of Publication). Title of article. Title of Newspaper. URL of newspaper's homepage

Rosenberg, G. (1997, March 31). Electronic discovery proves an effective legal weapon. The New York Times. http://www.nytimes.com

Notes: When citing a newspaper, keep in mind:

• If the article was found on the newspaper's website, include the URL for the newspaper's homepage. For databases, include whatever URL is provided.
• Multiple lines: If the URL runs onto a second line, only break URL before punctuation (except for http://).
• This style does NOT require you to include the date of access for electronic sources. If you discovered a newspaper article via an online database, the database's information is NOT required for the citation either. If you're using the BibMe APA formatter, we make it easy for you by only including what you need in your references!

Citations for Magazines

Citing a magazine article in print:

Author's Last name, F. M. (Year, Month of publication). Article title. Magazine Title, Volume (Issue), page range.

APA format citation:

Tumulty, K. (2006, April). Should they stay or should they go? Time, 167 (15), 3-40.

Notes: When citing a magazine, keep in mind:

• You can find the volume number with the other publication information of the magazine.
• You can typically find page numbers at the bottom corners of a magazine article.
• If you cannot locate an issue number, simply don't include it in the citation.

Citing a magazine article found online:

Author's Last name, F. M. (Year, Month of publication). Article title. Magazine Title, Volume (Issue). URL

Tumulty, K. (2006, April). Should they stay or should they go? Time, 167 (15). http://content.time.com/time/magazine/article/0,9171,1179361,00.html

Notes: When creating an online magazine citation, keep in mind:

*The volume and issue number aren't always on the same page as the article. Check out the other parts of the website before leaving it out of the citation.

Citations for Blogs

Blogs are found on websites and display continuously updated content and posts by a single author, group, or company. A blog shows news updates, ideas, information, and many other types of entries. Similar to journal entries, a blog begins with the date the information was added followed by the content.

If you’re wondering how to cite a blog entry, look no further! Citing a blog is very similar to citing a website.

Citing a blog post:

Last name of Author, First initial. Middle initial. (Year, Month Day blog post was published). Title of blog post. Title of Blog . URL

Gonzalez, J. (2019, February 3). Let’s give our teaching language a makeover. Cult of Pedagogy. https://www.cultofpedagogy.com/language-makeover/

Notice that the blog title only has a capital letter at the beginning. If there are any proper nouns in the title, capitalize the first letter for those as well.

Cite a blog post in the text of the paper:

(Author’s last name, Year)

Author’s last name (Year)

Citations for Research Reports

A research, or technical report, is a piece of work that provides insight into research done by an individual researcher, a group of researchers, or a company or organization.

Citing a research report in print:

Note: If you're discussing a certain part of the film or video in the body of your project, include a timestamp in the in-text or parenthetical citation. (Pulp Fiction, 1994, 1:15:30). The time stamp is Hours:Minutes:Seconds.

Citations for Images

Citing an image found in a print publication (such as a book or magazine) or museum:

Creator's Last name, F. M. (Year of Publication). Title of image [Format]. Publisher/Museum.

Including the format helps the reader understand and visualize the type of image that is being referenced. It can be [Photograph], [Painting], or another medium.

Citations for Songs

To cite in APA a song from an album listened to online, use the following structure:

Songwriter's Last name, F. M. (Copyright year). Title of song [Song recorded by F. M. Last name]. On Album title . Publisher. URL

• If the song is done by a band or group, include the band or group's name instead of an individual's name.
• Only include the "Recorded by F. M. Last name" portion if it's a different individual than the writer.
• The format can be CD, Online song, mp3, or any other simple description to allow the reader to understand the format.

If you're using the BibMe APA citation generator to build your references, choose "Music/Audio" from the source options.

Citations for Interviews

A personal interview should NOT be included in a reference list. They are not considered recoverable data (they cannot be found by a researcher). You should reference personal interviews as citations in the body of the project instead.

(J. Doe, personal communication, December 12, 2004)

Citations for Encyclopedia and Dictionary Entries

Encyclopedia/Dictionary in print:

Author's Last name, F. M. (Publication Year). Entry title. In F. M. Last name of Editor (Ed.), Title of encyclopedia or dictionary (pp. xx-xx). Publisher.

Kammen, C., & Wilson, A. H. (2012). Monuments. Encyclopedia of local history . (pp. 363-364). AltaMira Press.

Encyclopedia/Dictionary online with author(s) :

Author’s Last name, F. M. (Publication Year or n.d.). Entry title. In F. M. Last name of Editor (Ed.), Title of encyclopedia or dictionary . Publisher. Retrieved date, from URL

Encyclopedia/Dictionary online with group author:

Publisher or group name (Publication Year or n.d.). Entry title. In Title of encyclopedia or dictionary . Retrieved date, from URL

Merriam-Webster. (n.d.). Taciturn. In Merriam-Webster.com dictionary . Retrieved February 10, 2020, from https://www.merriam-webster.com/dictionary/taciturn

If an entry looks like it goes through many updates, use “n.d.” as the publication date and show the date you retrieved it. If using an archived version, no retrieval date is needed.

How to Reference a Lecture

This style of reference would be used if you were citing a set of notes from a lecture (e.g., PowerPoint or Google slides provided by your instructor).

Citing online lecture notes or presentation slides:

Author's Last name, F. M. (Publication year). Name or title of lecture [Lectures notes or PowerPoint slides]. URL

Saito, T. (2012). Technology and me: A personal timeline of educational technology [PowerPoint slides]. http://www.slideshare.net/Bclari25/educational-technology-ppt

Tip: If you want to cite information from your own personal notes from a lecture, this is considered personal communication. The notes may not be available online for others outside of the class to access. Refer to it only in the body of your essay or project. You can follow the style guide for personal communication available in the Interview section.

Citing Social Media

Social media is everywhere, even in research projects. Many influencers post thoughts, inspirational quotes, and intriguing stories in their profiles.

If you need to cite a post from a social media platform, use this structure:

Last name, F. M. or Group Name who posted the content [@Username]. (Year, Month Day posted). First 20 words of the post [Format]. Social Media Site Name. URL

A retrieval date (date you saw the page) is needed for profile pages since the contents are likely to change over time (e.g., Instagram profile, Facebook page etc.). The structure for that is:

Last name, F. M. or Group Name who posted the content [@Username]. (n.d.). Tweets or Home [Format]. Social Media Site Name. Retrieved from month day, year, URL

Some things to keep in mind:

• If the name of the individual or group is unknown, begin the citation with the handle and remove the brackets.
• If the post only includes an image or video without any text, instead of including the first 40 words of the post provide a description of the post and place it in brackets: [video of a NASA rocket leaving the atmosphere].
• The format, in brackets, can be [Tweet], [Facebook status update], [Facebook page], [Instagram photo], [Instagram video], or for a Reddit post, use [Online forum comment].

Since this citation style is commonly used in science-related disciplines, it makes sense that many students and scholars include tables in their projects.

It's a good idea to include a table in your project when:

• There is a good amount of quantitative information
• A table would promote understanding

Do not write out the information from the table in the text of your paper. Including the same information in two spots is repetitive. Either type out the quantitative information in your paper or use a table.

If you choose to include a table, make sure to:

• Refer to it in the text and provide a brief overview or snapshot of its contents.
• Refer to the table in the text using numbers. For example, "Table 3 shows the countries with the highest amount of spending per pupil."
• Every table should be numbered. The table mentioned closest to the beginning of the paper should be Table 1. The next table referred to in the paper is Table 2.
• If you're submitting your project for publication in a journal or elsewhere, place all of your tables, in number order, at the end of your project, after the reference list. If you're submitting your project for a class, most professors prefer tables to be situated close to mentions in text. Ask your teacher or professor which one they prefer.
• Each table needs a title. The title of the table should match the content displayed in it. Create a name for your table that is easy to understand. Italicize the title and capitalize the first letter of all major key words.
• Capitalize the first letter of every important word.
• Your table can either be single or double spaced. Keep the spacing in tables consistent throughout your project.
• A general note provides an overview of any information related to the table as well as an explanation of any abbreviations or unique characters. If you reproduced any portion of the table, include that information in the general note as well. Begin your general note with "Note." in italics and ending with period.
• A specific note explains information in a row, column, or individual cell. Place a tiny letter in the top right corner of the area to specify, and include information regarding it in the note below.
• A probability note displays the number of possibilities in the table. Use an asterisk symbol in the table, and show the probability in the notes.

Sample Table:

Prior to adding your table into your paper, use this handy checklist to confirm you have all of the requirements:

__ Is it necessary to include the table?

__ Are only horizontal lines included?

__ Did you include a simple, straightforward title? Is it in italics?

__ Did you use either single spaces or double spaces? APA paper format requires you to keep your tables consistent across your project.

__ Are column headings included?

__ Are notes included below the table to provide understanding? Are the notes in the proper order? Start with general notes, then include specific notes, and end with probability notes.

__ Did you refer to the table in the written portion of your paper?

Still have questions? See Chapter 7 of the Publication manual .

In-Text and Parenthetical Citations

What is an in-text citation or parenthetical citation.

The purpose of in-text and parenthetical citations is to give the reader a brief idea as to where you found your information, while they're in the middle of reading or viewing your project. You may include direct quotes in the body of your project, which are word-for-word quotes from another source. Or, you may include a piece of information that you paraphrased in your own words. These are called parenthetical citations. Both direct quotes and paraphrased information include a citation next to it. You also need to include the full citation for the source in the reference list, which is usually the last item in a project.

In-Text Citations for Direct Quotes

In-text and parenthetical citations are found immediately following any direct quotes or paraphrases. They should include the page number or section information to help the reader locate the quote themselves.

Buck needed to adjust rather quickly upon his arrival in Canada. He stated, "no lazy, sun-kissed life was this, with nothing to do but loaf and be bored. Here was neither peace, nor rest, nor a moment's safety" (London, 1903, p. 25).

Paraphrased Information

When taking an idea from another source and placing it in your own words (a paraphrase), it is not necessary to include the page number, but you can add it if the source is large and you want to direct readers right to the information.

At the time, papyrus was used to create paper, but it was only grown and available in mass quantities in Egypt. This posed a problem for the Greeks and Romans, but they managed to have it exported to their civilizations. Papyrus thus remained the material of choice for paper creation (Casson, 2001).

How to Format In-Text and Parenthetical Citations

An in-text citation in APA displays the author's name directly in the sentence, or text, of the paper. Always place the year directly after the author's name. Authors and dates stick together like peanut butter and jelly! If you're citing a direct quote, place the page number at the end of the quote.

Parenthetical citations display the author's name and year in parentheses after a quote or paraphrase. If you're citing a direct quote, include the page number as well. If you're paraphrasing, it is up to you whether or not you'd like to include a page number.

Example of various ways to cite in the body of a project:

Smith (2014) states that, "the Museum Effect is concerned with how individuals look at a work of art, but only in the context of looking at that work along with a number of other works" (p. 82). "The Museum Effect is concerned with how individuals look at a work of art, but only in the context of looking at that work along with a number of other works" (Smith, 2014, p. 82).

If your source has two authors, always include both names in each in-text or parenthetical citation.

Example: (Franks & Beans, 2019)

If your source has three or more authors, only include the first author's name and follow it with et al.

Example: (Gilley et al., 2015)

If your source was written by a company, organization, government agency, or other type of group, include the group's name in full in the first in text or parenthetical citation. In any APA citations following it, it is acceptable to shorten the group name to something that is simple and understandable.

1st citation:

(American Eagle Outfitters /[AEO/], 2017)

2nd and subsequent citations:

(AEO, 2017)

Your Reference List

The listing of all sources used in your project are found in the reference list, which is the last page or part of a project. Included in this reference list are all of the sources you quoted or paraphrased in the body of your paper. This means that every reference found in the reference list should have a matching in-text or parenthetical citation in your project. Where there is one, there has to be the other. Here are general guidelines:

• Your reference page in APA should be titled "References"
• Place the title in the center of the page and bold it.
• It is not necessary to include personal communications in the reference list, such as personal emails or letters. These specific sources only need in-text citations, which are found in the body of your project.
• All references are listed in alphabetical order by the author's last name.
• The entire page should be double spaced.
• Use a hanging indent for all citations. The first line of each citation needs to be flush against the left margin. Any additional lines are indented in a half inch.
• If you have two sources by the same author, place them in order by the year of publication.
• Refer to the section titled, "How to Structure the Title," for rules regarding capitalization of source titles.

Thompson, H. S. (1971). Fear and loathing in Las Vegas: A savage journey to the heart of the American dream . Random House.

Thompson, H. S. (1998). The rum diary . Simon & Schuster.

If there are multiple sources with the same author AND same publication date, place them in alphabetical order by the title.

Dr. Seuss. (1958). The cat in the hat comes back . Random House.

Dr. Seuss. (1958). Yertle the turtle . Random House.

If a source does not have an author, place the source in alphabetical order by the first main word of the title.

How to Format Your Paper in APA:

Need to create APA format papers? Follow these guidelines:

In an APA style paper, the font used throughout your document should be in Times New Roman, 12 point font size. The entire document should be double spaced, even between titles and APA headings. Margins should be 1 inch around the entire document and indent every new paragraph using the tab button on your keyboard. See Chapter 2 of the Publication manual for more details on paper formatting.

Place the pages in the following order:

• Title page (Page 1)
• Abstract page (page 2)
• Text or body of research paper (start on page 3)
• Reference list
• Page for tables (if necessary)
• Page for figures (if necessary)
• Appendices page (if necessary)

Page numbers: The title page counts as page 1. Number subsequent pages using Arabic numbers (1, 2, 3, 4...).

Title Page in APA

Your title page should grace the front cover of your paper. It's sometimes called an APA cover page. Included on this page are seven items:

• Page number
• Title of paper
• Name of authors
• Affiliation; name of your school or institution
• Course name
• Instructor's name
• Date paper is due

What is a running head?

The running head shows the title of your paper. It is only required for professional papers (e.g., dissertations, journal submissions, etc.).

Student papers do not need a running head (but do need the page number).

If you use one, place the running head in the top left corner of your project and place it in capital letters. Use your word processor's "header" option. It will automatically place your running head in the appropriate position, against the left margin.

Across from the running head, against the right margin, include the page number. The APA title page is 1.

Title page example:

• QUALITY LIBRARY PROGRAMS

Microsoft Word, Google Docs, and many other word processing programs allow you to set up page numbers and a repeated running head. Use these tools to make this addition easier for you!

Need help determining the title of your paper? Keep it simple and straight to the point. Exclude unnecessary terms such as "An Analysis of...." or "A Study of..." If your paper ends up being digitized and added to your school's research collection or a research database, a simple and effective title will help researchers locate it. It is recommended to keep it under 12 words and avoid abbreviations.

Order | Element | Format & Notes --- | --- | --- 0 | All elements, except page number | Centered, double-spaced lines 1 | Page number | Place “1” in the upper right corner of the page. Professional papers only: Include a running head. 2 | Title of paper | 3-4 lines from the top of the page; bolded, and title case 3 | Name of author(s) | Two double-spaced lines under the title. No font formatting (no bold italics, underline). Exclude any titles (such as Dr. or Ms.) and degrees (such as PhD). List all contributors; if there is more than one include the word “and” between the second to last and last names. 4 | Affiliation (school, department, etc.) | No font formatting. Usually includes the name of your department and university. 5 | Course name | No font formatting. Write the course name and number on your class materials: ENG 102, JPN301. 6 | Instructor | No font formatting. Show their name as they prefer, including titles and degrees. 7 | Date paper is due | Month Day, Year. Example: February 14, 2020

Levels of Headings:

There are a lot of rules to follow when it comes to styling the header and title page, but there are even more rules when it comes to styling the various headings and sections in your research paper.

There are five sizes and styles, and they follow a top down approach.

In most cases, science-related papers and case studies have three sections: Method, Results, and Discussion. These three sections are considered “Level 1” and are aligned in the center of the page and in bold. Additional sections of the paper are styled as follows:

Overview of Levels

Level | Formatting --- | --- 1 | Center and bold. Use title case. 2 | Against the left margin and in bold. Use title case. Begin the next sentence on the next line, indented half an inch from the left margin. 3 | Against the left margin in bold and italics. Use title case. Begin your next sentence on the next line, and indented half an inch from the left margin. 4 | Indented half an inch from the left. Is in bold. Use title case. Begin your next sentence on the same line and immediately following the heading. 5 | Indented half an inch from the left. Is in bold and italics. Use title case. Begin your next sentence on the same line and immediately following the heading.

We’ve included a visual below to help you make sense of the five headings. Keep in mind, you do not need to have all five headings in your paper. You may only use the top two or three. It depends on the types of sections your paper includes.

Background Information and History of APA:

The American Psychological Association was founded in 1892 at Clark University in Worcester, Massachusetts. APA style format was developed in 1929 by scholars from a number of different scientific fields and backgrounds. Their overall goal was to develop a standard way to document scientific writing and research.

Since its inception, the Style Manual has been updated numerous times and it is now in its 7th edition (2020). The previous 6th edition was released in 2009. In 2012, APA published an addition to their 6th edition manual, which was a guide for creating an APA style citation for any type of electronic resource.

Today, there are close to 118,000 members. There is an annual convention, numerous databases, and journal publications. Some of their more popular resources include the database, PsycINFO, and the publications, Journal of Applied Psychology and Health Psychology .

Changes Between the 6th and 7th Editions

Below is a selection of notable citing differences between the two editions.

Ethical Use

-- apa style, -- mla style, -- chicago style.

• Other AI Tools for Research
• Copyright and Data Privacy

Familiarize yourself with UP's policies on using AI . If you use a generative AI tool for writing, be transparent with your professors. Acknowledge your uses of the tool (such as editing your writing or translating words) within your paper, in a note, or in another suitable location like an appendix. 

Ethical Question:

• Should generative AIs be credited the same way as human authors? Citations are used to credit the work of other people and give readers a path to the sources used. A reader can then find and look at those sources to make their judgment on things like authority and accuracy. AI tools generate text in human language but may not accurately identify specific sources used. However, they can fabricate convincing citations to sources that don't exist. 

What can you do?

• Cite a generative AI tool when you paraphrase, quote, or incorporate other content (e.g., text, images, data) from it into your own work.
• Providing a record of chat prompts and responses can also be helpful for someone assessing your work. Take screenshots or provide share links (now available for  ChatGPT  and  Gemini ). 
• When it comes to finding reliable sources, use search tools and resources featured in our library guides . They are still the most effective way to find and connect to real published sources.

Guidance for citing ChatGPT and similar AI tools is emerging while continuing to be debated ( more from APA ).

Generate accurate Harvard reference lists quickly and for FREE, with MyBib!

🤔 What is a Harvard Referencing Generator?

A Harvard Referencing Generator is a tool that automatically generates formatted academic references in the Harvard style.

It takes in relevant details about a source -- usually critical information like author names, article titles, publish dates, and URLs -- and adds the correct punctuation and formatting required by the Harvard referencing style.

The generated references can be copied into a reference list or bibliography, and then collectively appended to the end of an academic assignment. This is the standard way to give credit to sources used in the main body of an assignment.

👩‍🎓 Who uses a Harvard Referencing Generator?

Harvard is the main referencing style at colleges and universities in the United Kingdom and Australia. It is also very popular in other English-speaking countries such as South Africa, Hong Kong, and New Zealand. University-level students in these countries are most likely to use a Harvard generator to aid them with their undergraduate assignments (and often post-graduate too).

🙌 Why should I use a Harvard Referencing Generator?

A Harvard Referencing Generator solves two problems:

• It provides a way to organise and keep track of the sources referenced in the content of an academic paper.
• It ensures that references are formatted correctly -- inline with the Harvard referencing style -- and it does so considerably faster than writing them out manually.

A well-formatted and broad bibliography can account for up to 20% of the total grade for an undergraduate-level project, and using a generator tool can contribute significantly towards earning them.

⚙️ How do I use MyBib's Harvard Referencing Generator?

Here's how to use our reference generator:

• If citing a book, website, journal, or video: enter the URL or title into the search bar at the top of the page and press the search button.
• Choose the most relevant results from the list of search results.
• Our generator will automatically locate the source details and format them in the correct Harvard format. You can make further changes if required.
• Then either copy the formatted reference directly into your reference list by clicking the 'copy' button, or save it to your MyBib account for later.

MyBib supports the following for Harvard style:

🍏 What other versions of Harvard referencing exist?

There isn't "one true way" to do Harvard referencing, and many universities have their own slightly different guidelines for the style. Our generator can adapt to handle the following list of different Harvard styles:

GPT-fabricated scientific papers on Google Scholar: Key features, spread, and implications for preempting evidence manipulation

Article metrics.

PDF Downloads

Academic journals, archives, and repositories are seeing an increasing number of questionable research papers clearly produced using generative AI. They are often created with widely available, general-purpose AI applications, most likely ChatGPT, and mimic scientific writing. Google Scholar easily locates and lists these questionable papers alongside reputable, quality-controlled research. Our analysis of a selection of questionable GPT-fabricated scientific papers found in Google Scholar shows that many are about applied, often controversial topics susceptible to disinformation: the environment, health, and computing. The resulting enhanced potential for malicious manipulation of society’s evidence base, particularly in politically divisive domains, is a growing concern.

Research Questions

• Where are questionable publications produced with generative pre-trained transformers (GPTs) that can be found via Google Scholar published or deposited?
• What are the main characteristics of these publications in relation to predominant subject categories?
• How are these publications spread in the research infrastructure for scholarly communication?
• How is the role of the scholarly communication infrastructure challenged in maintaining public trust in science and evidence through inappropriate use of generative AI?

research note Summary

• A sample of scientific papers with signs of GPT-use found on Google Scholar was retrieved, downloaded, and analyzed using a combination of qualitative coding and descriptive statistics. All papers contained at least one of two common phrases returned by conversational agents that use large language models (LLM) like OpenAI’s ChatGPT. Google Search was then used to determine the extent to which copies of questionable, GPT-fabricated papers were available in various repositories, archives, citation databases, and social media platforms.
• Roughly two-thirds of the retrieved papers were found to have been produced, at least in part, through undisclosed, potentially deceptive use of GPT. The majority (57%) of these questionable papers dealt with policy-relevant subjects (i.e., environment, health, computing), susceptible to influence operations. Most were available in several copies on different domains (e.g., social media, archives, and repositories).
• Two main risks arise from the increasingly common use of GPT to (mass-)produce fake, scientific publications. First, the abundance of fabricated “studies” seeping into all areas of the research infrastructure threatens to overwhelm the scholarly communication system and jeopardize the integrity of the scientific record. A second risk lies in the increased possibility that convincingly scientific-looking content was in fact deceitfully created with AI tools and is also optimized to be retrieved by publicly available academic search engines, particularly Google Scholar. However small, this possibility and awareness of it risks undermining the basis for trust in scientific knowledge and poses serious societal risks.

Implications

The use of ChatGPT to generate text for academic papers has raised concerns about research integrity. Discussion of this phenomenon is ongoing in editorials, commentaries, opinion pieces, and on social media (Bom, 2023; Stokel-Walker, 2024; Thorp, 2023). There are now several lists of papers suspected of GPT misuse, and new papers are constantly being added. 1 See for example Academ-AI, https://www.academ-ai.info/ , and Retraction Watch, https://retractionwatch.com/papers-and-peer-reviews-with-evidence-of-chatgpt-writing/ . While many legitimate uses of GPT for research and academic writing exist (Huang & Tan, 2023; Kitamura, 2023; Lund et al., 2023), its undeclared use—beyond proofreading—has potentially far-reaching implications for both science and society, but especially for their relationship. It, therefore, seems important to extend the discussion to one of the most accessible and well-known intermediaries between science, but also certain types of misinformation, and the public, namely Google Scholar, also in response to the legitimate concerns that the discussion of generative AI and misinformation needs to be more nuanced and empirically substantiated  (Simon et al., 2023).

Google Scholar, https://scholar.google.com , is an easy-to-use academic search engine. It is available for free, and its index is extensive (Gusenbauer & Haddaway, 2020). It is also often touted as a credible source for academic literature and even recommended in library guides, by media and information literacy initiatives, and fact checkers (Tripodi et al., 2023). However, Google Scholar lacks the transparency and adherence to standards that usually characterize citation databases. Instead, Google Scholar uses automated crawlers, like Google’s web search engine (Martín-Martín et al., 2021), and the inclusion criteria are based on primarily technical standards, allowing any individual author—with or without scientific affiliation—to upload papers to be indexed (Google Scholar Help, n.d.). It has been shown that Google Scholar is susceptible to manipulation through citation exploits (Antkare, 2020) and by providing access to fake scientific papers (Dadkhah et al., 2017). A large part of Google Scholar’s index consists of publications from established scientific journals or other forms of quality-controlled, scholarly literature. However, the index also contains a large amount of gray literature, including student papers, working papers, reports, preprint servers, and academic networking sites, as well as material from so-called “questionable” academic journals, including paper mills. The search interface does not offer the possibility to filter the results meaningfully by material type, publication status, or form of quality control, such as limiting the search to peer-reviewed material.

To understand the occurrence of ChatGPT (co-)authored work in Google Scholar’s index, we scraped it for publications, including one of two common ChatGPT responses (see Appendix A) that we encountered on social media and in media reports (DeGeurin, 2024). The results of our descriptive statistical analyses showed that around 62% did not declare the use of GPTs. Most of these GPT-fabricated papers were found in non-indexed journals and working papers, but some cases included research published in mainstream scientific journals and conference proceedings. 2 Indexed journals mean scholarly journals indexed by abstract and citation databases such as Scopus and Web of Science, where the indexation implies journals with high scientific quality. Non-indexed journals are journals that fall outside of this indexation. More than half (57%) of these GPT-fabricated papers concerned policy-relevant subject areas susceptible to influence operations. To avoid increasing the visibility of these publications, we abstained from referencing them in this research note. However, we have made the data available in the Harvard Dataverse repository.

The publications were related to three issue areas—health (14.5%), environment (19.5%) and computing (23%)—with key terms such “healthcare,” “COVID-19,” or “infection”for health-related papers, and “analysis,” “sustainable,” and “global” for environment-related papers. In several cases, the papers had titles that strung together general keywords and buzzwords, thus alluding to very broad and current research. These terms included “biology,” “telehealth,” “climate policy,” “diversity,” and “disrupting,” to name just a few.  While the study’s scope and design did not include a detailed analysis of which parts of the articles included fabricated text, our dataset did contain the surrounding sentences for each occurrence of the suspicious phrases that formed the basis for our search and subsequent selection. Based on that, we can say that the phrases occurred in most sections typically found in scientific publications, including the literature review, methods, conceptual and theoretical frameworks, background, motivation or societal relevance, and even discussion. This was confirmed during the joint coding, where we read and discussed all articles. It became clear that not just the text related to the telltale phrases was created by GPT, but that almost all articles in our sample of questionable articles likely contained traces of GPT-fabricated text everywhere.

Evidence hacking and backfiring effects

Generative pre-trained transformers (GPTs) can be used to produce texts that mimic scientific writing. These texts, when made available online—as we demonstrate—leak into the databases of academic search engines and other parts of the research infrastructure for scholarly communication. This development exacerbates problems that were already present with less sophisticated text generators (Antkare, 2020; Cabanac & Labbé, 2021). Yet, the public release of ChatGPT in 2022, together with the way Google Scholar works, has increased the likelihood of lay people (e.g., media, politicians, patients, students) coming across questionable (or even entirely GPT-fabricated) papers and other problematic research findings. Previous research has emphasized that the ability to determine the value and status of scientific publications for lay people is at stake when misleading articles are passed off as reputable (Haider & Åström, 2017) and that systematic literature reviews risk being compromised (Dadkhah et al., 2017). It has also been highlighted that Google Scholar, in particular, can be and has been exploited for manipulating the evidence base for politically charged issues and to fuel conspiracy narratives (Tripodi et al., 2023). Both concerns are likely to be magnified in the future, increasing the risk of what we suggest calling evidence hacking —the strategic and coordinated malicious manipulation of society’s evidence base.

The authority of quality-controlled research as evidence to support legislation, policy, politics, and other forms of decision-making is undermined by the presence of undeclared GPT-fabricated content in publications professing to be scientific. Due to the large number of archives, repositories, mirror sites, and shadow libraries to which they spread, there is a clear risk that GPT-fabricated, questionable papers will reach audiences even after a possible retraction. There are considerable technical difficulties involved in identifying and tracing computer-fabricated papers (Cabanac & Labbé, 2021; Dadkhah et al., 2023; Jones, 2024), not to mention preventing and curbing their spread and uptake.

However, as the rise of the so-called anti-vaxx movement during the COVID-19 pandemic and the ongoing obstruction and denial of climate change show, retracting erroneous publications often fuels conspiracies and increases the following of these movements rather than stopping them. To illustrate this mechanism, climate deniers frequently question established scientific consensus by pointing to other, supposedly scientific, studies that support their claims. Usually, these are poorly executed, not peer-reviewed, based on obsolete data, or even fraudulent (Dunlap & Brulle, 2020). A similar strategy is successful in the alternative epistemic world of the global anti-vaccination movement (Carrion, 2018) and the persistence of flawed and questionable publications in the scientific record already poses significant problems for health research, policy, and lawmakers, and thus for society as a whole (Littell et al., 2024). Considering that a person’s support for “doing your own research” is associated with increased mistrust in scientific institutions (Chinn & Hasell, 2023), it will be of utmost importance to anticipate and consider such backfiring effects already when designing a technical solution, when suggesting industry or legal regulation, and in the planning of educational measures.

Recommendations

Solutions should be based on simultaneous considerations of technical, educational, and regulatory approaches, as well as incentives, including social ones, across the entire research infrastructure. Paying attention to how these approaches and incentives relate to each other can help identify points and mechanisms for disruption. Recognizing fraudulent academic papers must happen alongside understanding how they reach their audiences and what reasons there might be for some of these papers successfully “sticking around.” A possible way to mitigate some of the risks associated with GPT-fabricated scholarly texts finding their way into academic search engine results would be to provide filtering options for facets such as indexed journals, gray literature, peer-review, and similar on the interface of publicly available academic search engines. Furthermore, evaluation tools for indexed journals 3 Such as LiU Journal CheckUp, https://ep.liu.se/JournalCheckup/default.aspx?lang=eng . could be integrated into the graphical user interfaces and the crawlers of these academic search engines. To enable accountability, it is important that the index (database) of such a search engine is populated according to criteria that are transparent, open to scrutiny, and appropriate to the workings of  science and other forms of academic research. Moreover, considering that Google Scholar has no real competitor, there is a strong case for establishing a freely accessible, non-specialized academic search engine that is not run for commercial reasons but for reasons of public interest. Such measures, together with educational initiatives aimed particularly at policymakers, science communicators, journalists, and other media workers, will be crucial to reducing the possibilities for and effects of malicious manipulation or evidence hacking. It is important not to present this as a technical problem that exists only because of AI text generators but to relate it to the wider concerns in which it is embedded. These range from a largely dysfunctional scholarly publishing system (Haider & Åström, 2017) and academia’s “publish or perish” paradigm to Google’s near-monopoly and ideological battles over the control of information and ultimately knowledge. Any intervention is likely to have systemic effects; these effects need to be considered and assessed in advance and, ideally, followed up on.

Our study focused on a selection of papers that were easily recognizable as fraudulent. We used this relatively small sample as a magnifying glass to examine, delineate, and understand a problem that goes beyond the scope of the sample itself, which however points towards larger concerns that require further investigation. The work of ongoing whistleblowing initiatives 4 Such as Academ-AI, https://www.academ-ai.info/ , and Retraction Watch, https://retractionwatch.com/papers-and-peer-reviews-with-evidence-of-chatgpt-writing/ . , recent media reports of journal closures (Subbaraman, 2024), or GPT-related changes in word use and writing style (Cabanac et al., 2021; Stokel-Walker, 2024) suggest that we only see the tip of the iceberg. There are already more sophisticated cases (Dadkhah et al., 2023) as well as cases involving fabricated images (Gu et al., 2022). Our analysis shows that questionable and potentially manipulative GPT-fabricated papers permeate the research infrastructure and are likely to become a widespread phenomenon. Our findings underline that the risk of fake scientific papers being used to maliciously manipulate evidence (see Dadkhah et al., 2017) must be taken seriously. Manipulation may involve undeclared automatic summaries of texts, inclusion in literature reviews, explicit scientific claims, or the concealment of errors in studies so that they are difficult to detect in peer review. However, the mere possibility of these things happening is a significant risk in its own right that can be strategically exploited and will have ramifications for trust in and perception of science. Society’s methods of evaluating sources and the foundations of media and information literacy are under threat and public trust in science is at risk of further erosion, with far-reaching consequences for society in dealing with information disorders. To address this multifaceted problem, we first need to understand why it exists and proliferates.

Finding 1: 139 GPT-fabricated, questionable papers were found and listed as regular results on the Google Scholar results page. Non-indexed journals dominate.

Most questionable papers we found were in non-indexed journals or were working papers, but we did also find some in established journals, publications, conferences, and repositories. We found a total of 139 papers with a suspected deceptive use of ChatGPT or similar LLM applications (see Table 1). Out of these, 19 were in indexed journals, 89 were in non-indexed journals, 19 were student papers found in university databases, and 12 were working papers (mostly in preprint databases). Table 1 divides these papers into categories. Health and environment papers made up around 34% (47) of the sample. Of these, 66% were present in non-indexed journals.

Finding 2: GPT-fabricated, questionable papers are disseminated online, permeating the research infrastructure for scholarly communication, often in multiple copies. Applied topics with practical implications dominate.

The 20 papers concerning health-related issues are distributed across 20 unique domains, accounting for 46 URLs. The 27 papers dealing with environmental issues can be found across 26 unique domains, accounting for 56 URLs.  Most of the identified papers exist in multiple copies and have already spread to several archives, repositories, and social media. It would be difficult, or impossible, to remove them from the scientific record.

As apparent from Table 2, GPT-fabricated, questionable papers are seeping into most parts of the online research infrastructure for scholarly communication. Platforms on which identified papers have appeared include ResearchGate, ORCiD, Journal of Population Therapeutics and Clinical Pharmacology (JPTCP), Easychair, Frontiers, the Institute of Electrical and Electronics Engineer (IEEE), and X/Twitter. Thus, even if they are retracted from their original source, it will prove very difficult to track, remove, or even just mark them up on other platforms. Moreover, unless regulated, Google Scholar will enable their continued and most likely unlabeled discoverability.

A word rain visualization (Centre for Digital Humanities Uppsala, 2023), which combines word prominences through TF-IDF 5 Term frequency–inverse document frequency , a method for measuring the significance of a word in a document compared to its frequency across all documents in a collection. scores with semantic similarity of the full texts of our sample of GPT-generated articles that fall into the “Environment” and “Health” categories, reflects the two categories in question. However, as can be seen in Figure 1, it also reveals overlap and sub-areas. The y-axis shows word prominences through word positions and font sizes, while the x-axis indicates semantic similarity. In addition to a certain amount of overlap, this reveals sub-areas, which are best described as two distinct events within the word rain. The event on the left bundles terms related to the development and management of health and healthcare with “challenges,” “impact,” and “potential of artificial intelligence”emerging as semantically related terms. Terms related to research infrastructures, environmental, epistemic, and technological concepts are arranged further down in the same event (e.g., “system,” “climate,” “understanding,” “knowledge,” “learning,” “education,” “sustainable”). A second distinct event further to the right bundles terms associated with fish farming and aquatic medicinal plants, highlighting the presence of an aquaculture cluster.  Here, the prominence of groups of terms such as “used,” “model,” “-based,” and “traditional” suggests the presence of applied research on these topics. The two events making up the word rain visualization, are linked by a less dominant but overlapping cluster of terms related to “energy” and “water.”

The bar chart of the terms in the paper subset (see Figure 2) complements the word rain visualization by depicting the most prominent terms in the full texts along the y-axis. Here, word prominences across health and environment papers are arranged descendingly, where values outside parentheses are TF-IDF values (relative frequencies) and values inside parentheses are raw term frequencies (absolute frequencies).

Finding 3: Google Scholar presents results from quality-controlled and non-controlled citation databases on the same interface, providing unfiltered access to GPT-fabricated questionable papers.

Google Scholar’s central position in the publicly accessible scholarly communication infrastructure, as well as its lack of standards, transparency, and accountability in terms of inclusion criteria, has potentially serious implications for public trust in science. This is likely to exacerbate the already-known potential to exploit Google Scholar for evidence hacking (Tripodi et al., 2023) and will have implications for any attempts to retract or remove fraudulent papers from their original publication venues. Any solution must consider the entirety of the research infrastructure for scholarly communication and the interplay of different actors, interests, and incentives.

We searched and scraped Google Scholar using the Python library Scholarly (Cholewiak et al., 2023) for papers that included specific phrases known to be common responses from ChatGPT and similar applications with the same underlying model (GPT3.5 or GPT4): “as of my last knowledge update” and/or “I don’t have access to real-time data” (see Appendix A). This facilitated the identification of papers that likely used generative AI to produce text, resulting in 227 retrieved papers. The papers’ bibliographic information was automatically added to a spreadsheet and downloaded into Zotero. 6 An open-source reference manager, https://zotero.org .

We employed multiple coding (Barbour, 2001) to classify the papers based on their content. First, we jointly assessed whether the paper was suspected of fraudulent use of ChatGPT (or similar) based on how the text was integrated into the papers and whether the paper was presented as original research output or the AI tool’s role was acknowledged. Second, in analyzing the content of the papers, we continued the multiple coding by classifying the fraudulent papers into four categories identified during an initial round of analysis—health, environment, computing, and others—and then determining which subjects were most affected by this issue (see Table 1). Out of the 227 retrieved papers, 88 papers were written with legitimate and/or declared use of GPTs (i.e., false positives, which were excluded from further analysis), and 139 papers were written with undeclared and/or fraudulent use (i.e., true positives, which were included in further analysis). The multiple coding was conducted jointly by all authors of the present article, who collaboratively coded and cross-checked each other’s interpretation of the data simultaneously in a shared spreadsheet file. This was done to single out coding discrepancies and settle coding disagreements, which in turn ensured methodological thoroughness and analytical consensus (see Barbour, 2001). Redoing the category coding later based on our established coding schedule, we achieved an intercoder reliability (Cohen’s kappa) of 0.806 after eradicating obvious differences.

The ranking algorithm of Google Scholar prioritizes highly cited and older publications (Martín-Martín et al., 2016). Therefore, the position of the articles on the search engine results pages was not particularly informative, considering the relatively small number of results in combination with the recency of the publications. Only the query “as of my last knowledge update” had more than two search engine result pages. On those, questionable articles with undeclared use of GPTs were evenly distributed across all result pages (min: 4, max: 9, mode: 8), with the proportion of undeclared use being slightly higher on average on later search result pages.

To understand how the papers making fraudulent use of generative AI were disseminated online, we programmatically searched for the paper titles (with exact string matching) in Google Search from our local IP address (see Appendix B) using the googlesearch – python library(Vikramaditya, 2020). We manually verified each search result to filter out false positives—results that were not related to the paper—and then compiled the most prominent URLs by field. This enabled the identification of other platforms through which the papers had been spread. We did not, however, investigate whether copies had spread into SciHub or other shadow libraries, or if they were referenced in Wikipedia.

We used descriptive statistics to count the prevalence of the number of GPT-fabricated papers across topics and venues and top domains by subject. The pandas software library for the Python programming language (The pandas development team, 2024) was used for this part of the analysis. Based on the multiple coding, paper occurrences were counted in relation to their categories, divided into indexed journals, non-indexed journals, student papers, and working papers. The schemes, subdomains, and subdirectories of the URL strings were filtered out while top-level domains and second-level domains were kept, which led to normalizing domain names. This, in turn, allowed the counting of domain frequencies in the environment and health categories. To distinguish word prominences and meanings in the environment and health-related GPT-fabricated questionable papers, a semantically-aware word cloud visualization was produced through the use of a word rain (Centre for Digital Humanities Uppsala, 2023) for full-text versions of the papers. Font size and y-axis positions indicate word prominences through TF-IDF scores for the environment and health papers (also visualized in a separate bar chart with raw term frequencies in parentheses), and words are positioned along the x-axis to reflect semantic similarity (Skeppstedt et al., 2024), with an English Word2vec skip gram model space (Fares et al., 2017). An English stop word list was used, along with a manually produced list including terms such as “https,” “volume,” or “years.”

Why Do I Need to Cite?

Essentially, citing is the crediting of sources used in academic work. When another source contributes to your work you must acknowledge the original author with an accurate reference, unless it is common knowledge (e.g., the Magna Carta was signed in 1215). Failing to cite all of your sources or citing them incorrectly constitutes plagiarism , which is considered a serious academic offense. It is important to remember that information doesn’t just belong to anyone who happens to stumble upon it. If you are caught plagiarizing it is more than likely that you will lose points on your assignment, or even face expulsion from your university.

APA citation format also stipulates that students and researchers should be wary of a type of plagiarism called “self-plagiarism.” This is when you reuse material that you previously wrote for a new writing assignment without signaling to the reader that you have done so by creating an APA format citation for your work. Presenting your own past work as new scholarship is still plagiarism, and could still have serious consequences.

Aside from avoiding plagiarism, attributing your research to its proper source is crucial in ensuring that your work is firmly anchored in academic tradition. Correctly citing your sources validates the statements and conclusions you make in your work by providing supporting evidence. For many students, citing can be a frustrating process, but it’s an excellent way to enhance the quality of your work and inject it with authority.

Imagine if all the stress of referencing simply vanished. Well, Cite This For Me’s APA citation generator is here to help you make that stress disappear – now you can create in-text citations and reference lists in the APA format without all of the usual frustrations of referencing.

What is the APA Citation Style?

The APA citation style is a parenthetical author-date style, meaning that you need to put the author’s last name and the publishing date into parentheses wherever another source is used in the narrative.

The APA format consists of in-text citations and a reference list, along with guidelines for formatting the paper itself. Both the in-text citations and the reference list can be created in the blink of an eye using the Cite This For Me APA reference generator.

Although primarily used by students and researchers studying the social and behavioral sciences, the APA format is used amongst other scientific publications for its editorial efficiency. The Cite This For Me APA citation generator uses an up to date version of the APA format, helping to ensure accuracy whether you are using the APA format generator for university assignments or are preparing research projects for publishing.

Aside from the APA format, there is a plethora of different citation styles out there – the use of which depends on your discipline, university requirements, your professor’s preference, or the publication you are submitting the work to. It is important to make sure that you are using the correct style – so if you’re unsure, consult your department and follow their guidelines exactly.

It is important to note that APA style citation rules are fundamentally an editorial style, not a writing style per se. An editorial style refers to rules and guidelines a publisher uses to ensure that materials in their publications are presented consistently.

The citation generator above will generate your references in APA format as standard, and can show you how to cite APA sources in a few clicks. You can also sign up to Cite This For Me to select from thousands of widely used global college styles, including individual university variations. So, whether your professor prefers that you use the MLA format , or your discipline requires you to adopt the Chicago style citation , your referencing will be supported. Cite This For Me includes citation generators and handy guides for styles such as ASA , AMA or IEEE .

How Do I Create and Format My Citations?

Ever find yourself searching the web for things like “How to cite a website APA?” Then you’re in the right place. When you reference a source within an APA style paper; whether it is using a direct quote, repurposing an image, or simply referring to an idea or theory, you should:

• Insert an in-text citation (the author’s surname and the date of publication within parentheses) straight after a direct quote
• Insert an in-text citation at the end of the sentence where a source has contributed, but was not a direct quote
• If you have already mentioned the author’s name in the sentence, you only need to insert the date immediately after their surname
• Include page numbers within the parentheses (after the date), if referring to a particular page or section of the source
• When citing a source with three to five authors, include all surnames for the first in-text citation, then use the first author’s surname followed by et al. for subsequent citations
• When citing six or more authors – use the first author’s surname followed by et al. for all citations
• If you are mentioning both the year and author in the text, don’t include an additional citation in parentheses – unless you are referring to a particular section of the source, in which case you should cite the page number
• Provide an alphabetical list (ordered by author’s surname) of all sources used, titled ‘References’, on a separate page at the end of the narrative
• Inclusive page numbers for the electronic version of a print source (i.e., a PDF)
• Provide your appendices on a separate page after the reference list
• Use ‘&’ in place of ‘and’ in both in-text citations and full references

Use the Cite This For Me APA citation maker to create citations with ease; this will allow you to add citations to your project, edit on the spot, and export separate in-text citations as well as fully-formatted reference lists.

How Do I Format My Reference List?

Drawing on a range of relevant sources in your work proves that you have read widely around your chosen topic, so it’s a surefire way to impress your reader.

To ensure your reader’s ease of comprehension you must adhere to the style’s formatting guidelines. In APA format, a list of all the sources that have directly contributed to your work should be placed on a new page at the end of the narrative and titled ‘References’ (center align the title), otherwise known as an APA works cited list. The references should all have a hanging indentation – the second and subsequent lines of each reference should start ½ inch from the margin.

You may also be required to provide a full APA bibliography. This is a comprehensive list of all the source material you used to complete the assignment, even if it was not cited in the text. It should include any book, journal, article etc. that you may have consulted throughout your research and writing process in order to get a deeper understanding of the subject at hand.

APA Format Example:

Sound like a lot of work? Although the style guidelines are strict in regard to how references should be formatted, the Cite This For Me APA citation machine can help take the weight off your shoulders by quickly compiling your reference list and bibliography.

APA Style Paper Formatting Guidelines (7th Edition)

When following the APA format guidelines, you must pay attention to presentation details such as font type, line spacing, margins and page headers to ensure your work is easily legible. The information below, as well as further formatting details, can be found in Chapter 2 of the APA 7 Publication Manual .

• 1-inch margins on all sides
• Easily readable font – Times New Roman recommended, 12pt. size
• Double-space the entirety of the paper
• Page numbers in the header, aligned to the right
• Title of the paper in all capitals, 50 characters or less, in the header on each page of the body (the ‘running head’), aligned to the left. Only include a running head if you’re writing a professional paper
• The paper should typically include four major sections – Title Page, Abstract, Main Body and References.
• If infographics (tables, charts) were used in the narrative you should also add Appendices as a separate section at the end of the paper.

APA Title Page

Not all instructors will require a title page, also sometimes called an APA cover page. If they do, include these four parts:

• Title of your paper
• Running head (see above section)
• Author’s/Your name
• Institutional affiliation

The title of your paper should:

• Be centered on the page and use title case (a combination of lower and uppercase letters).
• Not be italicized, bolded, or underlined
• Use a 12-point font
• Be a maximum of 2 lines and not more than 12 words long
• Not include abbreviations

Underneath the title, place the author’s name. If you wrote the paper, put your full name here. There’s no need to include titles or degrees (e.g., Ms., PhD, etc.).

Under the author’s name, place the institutional affiliation. For most students, this would be the name of the school, college or university you are attending. The title, author’s name, and institutional affiliation should all be double spaced. Here’s an example of an APA format title page:

Writing Guidelines

The American Psychological Association also provides some helpful guidelines regarding overall best practices when writing academic and scientific papers. One important thing to be on the lookout for is bias in your writing. For instance, using the word “man” to represent humans as a species is neither scientific nor without potential bias.

Here are some good rules of thumb to help you avoid bias in your paper:

• Always be specific in your writing and avoid generalizations.
• Do not label people or test subjects unnecessarily.
• When writing about participants in your experiment or study, be sure to acknowledge them as such appropriately. Use the term “participants” instead of “subjects.”
• Use active voice instead of passive voice in your writing. For example, “the participants completed the task” vs. “the task was completed by the participants.”
• Always be cautious when discussing topics such as sexual orientation, racial and ethnic identity, disabilities, etc.
• Never change quotations to better serve your own ends or to better fit with your conclusions.

Important Terms for an APA Paper

Have you come across terms such as “abstract” or “appendices” in the manual and been unsure of their meanings? Here are some important terms to know when writing your next APA paper.

• Abstract – A brief and concise summary of your paper’s contents.
• Keywords – A list of significant keywords that the reader should be on the lookout for in your paper.
• Introduction – Generally kicks of the rest of your paper by describing what you’re writing about. In scientific papers, this would outline the problem you are solving and your research strategy.
• References – An APA reference page is the place where you list each source that you have cited via an APA in-text citation within the body of your paper.
• Running Head – Running head is the name of APA headings that are used in research papers. They contain the title of the paper, the page number, and the term “Running head.”

A Brief History of the APA Format

APA stands for American Psychological Association , the scientific organization that assembles the publishing manual of the APA format. The style was developed in 1929 by a group of scientists to standardize scientific writing. It was created in the hopes that it would provide a coherent and professional manner of citing sources for students and researchers in the fields of social and behavioral sciences.

The first publication manual of the APA format was published in pursuit of a neat and efficient research formatting style, mainly for editorial purposes. Although some contemporary scientists argued that having such strict regulations restricted personal writing styles, the format has since become one of the most popular referencing styles. Today it is adopted in term papers, research reports, literature reviews, theoretical articles, case studies etc.

What’s New in the 7th Edition of APA Format?

It is important to note that citation styles and referencing formats change over time as they adapt to new source types and trends in academic publishing. APA format is no different, and in the fall of 2019 released the 7th edition of its Publication Manual.

Are you curious to know what the differences are between the 7th and 6th edition of APA style? Here are some of the important updates listed in the 7th edition of APA citing:

• The location of the source’s publisher no longer needs to be included in the citation.
• DOIs are formatted as URLs (i.e. https://doi.org/xxx), and no longer require the label “DOI” preceding them in the reference.
• When making an APA website citation, URLs no longer need to be preceded by “Retrieved from.” The exception to this is when you include a date of retrieval, which is optional.
• When making an APA book citation for an ebook, you no longer need to include the device or platform that you read the book on (i.e. “Kindle) is no longer required in the citation.
• There is more flexibility in the 7th edition regarding APA paper format specifications on font.
• The running head in an APA format title page no longer requires the words “Running head,” and instead now only requires a page number and a shortened version of your paper’s title.
• You now need to only use one space after each period in your paper.

Before you switch to the newest version, it is a good idea to confirm with your teacher or instructor that this is the version of the style that they prefer you use.

Section 8.17 of the APA Manual, 7 th edition, provides details on the number of authors to be included in in-text citations. As per this section, any work having 3 or more authors will not be written fully. Instead, the Latin words “et al” meaning “and others” have to be used after writing the first author’s name.

Example In-Text Citation Entry for more than 3 authors:

Almost all suppressed persons end up becoming an oppressed person when the same set of situations is presented in their lives (Camus et al., 1975).

In a rare instance, multiple sets of three or more authors might have the same initial pair or initial author. Under such rare situations, Section 8.18 of the APA manual requires you to write out the names of authors in order to distinguish between such confusing references.

Example In-Text Citation Entries:

Bandopadhyay, Schmidt, Wagner et al. (2000)

Bandopadhyay, Schmidt, Meyer et al. (1975)

Section 2.8 of the APA Manual, 7 th edition, provides details on the running head. A shortened version of the paper’s title (50 characters or fewer, including spaces and punctuation), the running head appears on top of each page so that the readers can connect the paper’s content with the title. While running heads are not required for student papers unless explicitly stated by the organization or instructor, manuscripts for publication absolutely require them.

Running heads should be in all-capital letters, flush left (directly across from the page number, which is flush right), and presented in the page header including the title page. You do not need to use the words, “Running head” because it is implied from its presence in the header.

Section 2.3 of the APA Manual, 7 th edition provides details on what should appear in a title page for both professionals and students. While students are advised to follow the guidelines from their respective institutions or instructors, the following elements (from top to bottom) are necessary in the absence of any such information.

• Page number at the right hand side top in the header portion (also to be included in all pages)
• Title of the paper in bold, centered and appearing in the middle
• Author’s name
• Affiliation of the author (this will be the university’s name along with the department’s or division’s name)
• Name of the course (format used in the course materials. For example, PSY101)
• Name of the instructor (check with the instructor for their preference of salutation like Dr., Professor, etc.)
• Due date of the assignment with the month spelled out (June 1, 2021, or 1 June, 2021)

Section 2.3 of the APA Manual, 7 th edition provides details on what should appear on a title page for both professional and student papers. The following elements (from top to bottom) are necessary for the professional version of the title page.

• Running head in capitals at the left-hand side of the header portion (included on every page)
• Page number at the right-hand side of the header portion (included on every page)
• Title of the paper in bold, centered, and on the upper portion of the page (usually three or four lines down from the top)
• Authors’ name(s) in full, including first name, middle initial, and last name
• Affiliation of the authors (the university’s or institution’s name where the work referenced in the paper was conducted and the department’s or division’s name)
• Author Note (below the information listed above, this section provides additional pertinent information about authors along with contact information for those interested)

According to section 9.16 of the APA manual, 7th edition, you only need to add “retrieved from” and a retrieval date in a reference entry for web sources designed to be continuously updated. For example, an online reference entry from a dictionary or encyclopedia, or a social media page. Including a retrieval date signals to readers that the source may differ in content if retrieved on a different date. When including the retrieval date, insert it before the URL or DOI at the end of the entry:

Retrieved January 1, 2022, from https://chegg.com

For web sources with stable URLs or DOIs that do not change, do not include a retrieval date. Only include the URL or DOI. Section 9.5 of the APA manual, 7 th edition provides information on how to format DOIs (Digital Object Identifiers) and URLs (Uniform Resource Locators). Both DOIs and URLs are to be presented as hyperlinks (use http:// or https:// as the case may be). Since these are presented as hyperlinks that the readers can use to access the content, it is NOT necessary to have the words, “Retrieved from” or “Accessed from” before a DOI or an URL. However, test the resource to ensure the hyperlink works.

Section 8.11 of the APA Publication Manual , 7 th edition, provides details on parenthetical citations. A parenthetical citation provides the authors’ names and publication date of the source within parentheses along with the cited text. If two authors are present in the source, both authors’ last names should be mentioned in the in-text citation. Their names should be separated by an ampersand (&). The publication date should follow the second surname, separated by a comma.

A parenthetical citation can appear either at the end of the sentence or within the sentence depending on how the sentence is framed. The period or end punctuation appears after the closing parenthesis.

Example parenthetical citation at the end of a sentence:

The reach of fake news is greatly underrated (Rameses & Hudgson, 2021).

If more text appears along with the parenthetical citation, include commas to separate the year and help the reader distinguish the citation from the surrounding text.

Example parenthetical citation with additional text:

The reach of fake news is greatly underrated (see Rameses & Hudgson, 2021, for more detail).

Section 8.11 of the APA Publication Manual , 7 th edition, provides details on narrative citations. A narrative citation provides the authors’ names in running text, and the publication date appears within parentheses immediately after the names. If two authors are present in the source, both authors’ last names should be mentioned in the in-text citation. In narrative citations, the word “and” should be spelled out between the two names.

Example narrative citation with two authors:

Crompton and Williams (2020) noted that gut health is of paramount importance in maintaining mental health.

In some circumstances, the year may also appear within the text along with the authors’ names. In such a scenario, the date should not appear within parentheses.

Example narrative citation with two authors and date:

In 2020, Crompton and Williams broke new ground with their hypothesis that mental health is strongly linked with gut health.

As per Section 2.4 of the APA Publication Manual , 7 th edition, the title of a research paper should summarize the main idea in a succinct manner. While there is no prescribed title length in APA style, authors are advised to keep their titles brief and focused. The manual also provides examples between effective and ineffective titles, including “fluff” words that can be cut from titles and substantive information that should be included in a title to make it relevant to the reader(s).

When the whole book or article is being referenced, there is no need to include a page number. However, when you are referring to a specific page or pages (either in a paraphrase or a direct quote), include the page number(s) in your in-text citation.

If you are referring to information or a quote contained on a single page, add the page number after the author and date, preceded by “p.” If you are citing multiple pages, the page numbers should be preceded by “pp.” and separated by an en-dash.

Example in-text citation with single page number:

(Rayden, 2014, p. 308)

Example in-text citation with page range:

(Rayden, 2014, pp. 308-311)

If there are no page numbers in a work, you can use some other type of locator in in-text citations to help your reader find the information you are citing, like chapter names, headings, or paragraph numbers.

As per Section 8.14 of the APA Publication Manual , 7 th edition, for sources with an unknown author, include the title of the source and year of publication in your in-text citations instead.

If the title of the source is italicized in your reference list, it should also be italicized in your in-text citation. If the title is not in italics in the reference list, it should be in quotation marks in your in-text citation. Titles should be listed in title case (with all important words capitalized) when included in in-text citations.

In-text citation templates:

( Full Name of the Source , year)

(“Full Name of the Source,” year)

In-text citation examples:

( How to Be Awesomely You , 2021)

(“Social Dynamics in US Colleges,” 2018)

If a work’s author is designated as “Anonymous,” use “Anonymous” as the author in in-text citations, as shown below.

(Anonymous, 2020)

As per Section 2.14 of the APA Publication Manual , 7 th edition, an appendix or appendices are included after the references, footnotes, tables, and figures of the paper. In other words, appendices are the last item in your paper. Each appendix should be separately mentioned within the main text (e.g., “see Appendix A”). Appendices are to be self-contained; they should describe the contents and clearly have a label and title.

For a parenthetical in-text citation in APA style, the basic elements needed are the author’s last name (or the group author’s name) and the publication year. For parenthetical citations, format this information by inputting it in parentheses.

For a narrative in-text citation, include the information in the running text. Usually, this means you include the author’s last name followed by the year in parentheses. However, if needed, you may include both the author’s last name and the year in the running text.

For audio, visual, or audiovisual works, replace the author’s last name with a director’s last name (for a film), an uploader’s last name (for YouTube), the artist’s name (for an artwork), and so on.

As per section 2 of the APA 7 manual, papers require the following elements presented in the order below. Since the required elements differ depending on whether your paper is a professional or student paper, there are two lists to distinguish the differences. Sections like Figures, Tables, and Appendices may not be relevant to your paper, so you may exclude those.

Professional Papers*

• Title Page (with title, author(s), affiliations, and an author note)
• Page Headers including a running head and page numbers
• Reference List
• Keywords (optional)
• Footnotes (optional)
• Tables (optional)
• Figures (optional)
• Appendices (optional)
• Supplemental Materials (optional)

*Always refer to the professional journal’s instructions or submission guidelines.

Student Papers

• Page Numbers

An APA reference list comprises the publication details of the studies that specifically quote or support the ideas and concepts presented in a paper. Cite sources in the text, with a narrative or parenthetical citation, and include corresponding reference entries in the reference list.

An APA bibliography is similar to a reference list because it also includes full reference entries for sources cited in the text. However, they also include other sources that support or give background for further research related to the listed source.

An APA annotated bibliography includes short annotations below the reference entry in a separate paragraph(s). Annotations summarize and/or describe a source in detail.

Both the 6 th and 7 th editions of APA style are available on the Cite This For Me citation generator .

For a webpage/website, journal article, or book, you’ll need 1-2 pieces of basic publication information. For example:

• Website : URL, page title, etc.
• Journal article : Article title, DOI number, author(s), etc.
• Book : Book title, author, date published, etc.

Using those pieces of information, you can search for the source in the Cite This For Me APA citation generator and it will help you to create a citation.

Other source types (newspaper article, video, government document, etc.) will provide a form on which you provide all source information. Using that information, the citation generator will create a properly formatted APA citation for you.

Title: text-to-image generation via energy-based clip.

Abstract: Joint Energy Models (JEMs), while drawing significant research attention, have not been successfully scaled to real-world, high-resolution datasets. We present EB-CLIP, a novel approach extending JEMs to the multimodal vision-language domain using CLIP, integrating both generative and discriminative objectives. For the generative objective, we introduce an image-text joint-energy function based on Cosine similarity in the CLIP space, training CLIP to assign low energy to real image-caption pairs and high energy otherwise. For the discriminative objective, we employ contrastive adversarial loss, extending the adversarial training objective to the multimodal domain. EB-CLIP not only generates realistic images from text but also achieves competitive results on the compositionality benchmark, outperforming leading methods with fewer parameters. Additionally, we demonstrate the superior guidance capability of EB-CLIP by enhancing CLIP-based generative frameworks and converting unconditional diffusion models to text-based ones. Lastly, we show that EB-CLIP can serve as a more robust evaluation metric for text-to-image generative tasks than CLIP.

How to Cite Sources | Citation Generator & Quick Guide

Citing your sources is essential in  academic writing . Whenever you quote or paraphrase a source (such as a book, article, or webpage), you have to include a  citation crediting the original author.

Failing to properly cite your sources counts as plagiarism , since you’re presenting someone else’s ideas as if they were your own.

The most commonly used citation styles are APA and MLA. The free Scribbr Citation Generator is the quickest way to cite sources in these styles. Simply enter the URL, DOI, or title, and we’ll generate an accurate, correctly formatted citation.

Other useful citation tools

Citation examples and full guides, frequently asked questions about citing sources.

Citations are required in all types of academic texts. They are needed for several reasons:

• To avoid plagiarism by indicating when you’re taking information from another source
• To give proper credit to the author of that source
• To allow the reader to consult your sources for themselves

A citation is needed whenever you integrate a source into your writing. This usually means quoting or paraphrasing:

• To quote a source , copy a short piece of text word for word and put it inside quotation marks .
• To paraphrase a source , put the text into your own words. It’s important that the paraphrase is not too close to the original wording. You can use the paraphrasing tool if you don’t want to do this manually.

Citations are needed whether you quote or paraphrase, and whatever type of source you use. As well as citing scholarly sources like books and journal articles, don’t forget to include citations for any other sources you use for ideas, examples, or evidence. That includes websites, YouTube videos , and lectures .

Scribbr Citation Checker New

The AI-powered Citation Checker helps you avoid common mistakes such as:

• Missing commas and periods
• Incorrect usage of “et al.”
• Ampersands (&) in narrative citations
• Missing reference entries

Usually, your institution (or the journal you’re submitting to) will require you to follow a specific citation style, so check your guidelines or ask your instructor.

In some cases, you may have to choose a citation style for yourself. Make sure to pick one style and use it consistently:

• APA Style is widely used in the social sciences and beyond.
• MLA style is common in the humanities.
• Chicago notes and bibliography , common in the humanities
• Chicago author-date , used in the (social) sciences
• There are many other citation styles for different disciplines.

If in doubt, check with your instructor or read other papers from your field of study to see what style they follow.

In most styles, your citations consist of:

• Brief in-text citations at the relevant points in the text
• A reference list or bibliography containing full information on all the sources you’ve cited

In-text citations most commonly take the form of parenthetical citations featuring the last name of the source’s author and its year of publication (aka author-date citations).

An alternative to this type of in-text citation is the system used in numerical citation styles , where a number is inserted into the text, corresponding to an entry in a numbered reference list.

There are also note citation styles , where you place your citations in either footnotes or endnotes . Since they’re not embedded in the text itself, these citations can provide more detail and sometimes aren’t accompanied by a full reference list or bibliography.

A reference list (aka “Bibliography” or “Works Cited,” depending on the style) is where you provide full information on each of the sources you’ve cited in the text. It appears at the end of your paper, usually with a hanging indent applied to each entry.

The information included in reference entries is broadly similar, whatever citation style you’re using. For each source, you’ll typically include the:

• Author name
• Publication date
• Container (e.g., the book an essay was published in, the journal an article appeared in)
• Location (e.g., a URL or DOI , or sometimes a physical location)

The exact information included varies depending on the source type and the citation style. The order in which the information appears, and how you format it (e.g., capitalization, use of italics) also varies.

Most commonly, the entries in your reference list are alphabetized by author name. This allows the reader to easily find the relevant entry based on the author name in your in-text citation.

In numerical citation styles, the entries in your reference list are numbered, usually based on the order in which you cite them. The reader finds the right entry based on the number that appears in the text.

Because each style has many small differences regarding things like italicization, capitalization , and punctuation , it can be difficult to get every detail right. Using a citation generator can save you a lot of time and effort.

Scribbr offers citation generators for both APA and MLA style. Both are quick, easy to use, and 100% free, with no ads and no registration required.

Just input a URL or DOI or add the source details manually, and the generator will automatically produce an in-text citation and reference entry in the correct format. You can save your reference list as you go and download it when you’re done, and even add annotations for an annotated bibliography .

Once you’ve prepared your citations, you might still be unsure if they’re correct and if you’ve used them appropriately in your text. This is where Scribbr’s other citation tools and services may come in handy:

At college level, you must properly cite your sources in all essays , research papers , and other academic texts (except exams and in-class exercises).

Add a citation whenever you quote , paraphrase , or summarize information or ideas from a source. You should also give full source details in a bibliography or reference list at the end of your text.

The exact format of your citations depends on which citation style you are instructed to use. The most common styles are APA , MLA , and Chicago .

The abbreviation “ et al. ” (Latin for “and others”) is used to shorten citations of sources with multiple authors.

“Et al.” is used in APA in-text citations of sources with 3+ authors, e.g. (Smith et al., 2019). It is not used in APA reference entries .

Use “et al.” for 3+ authors in MLA in-text citations and Works Cited entries.

Use “et al.” for 4+ authors in a Chicago in-text citation , and for 10+ authors in a Chicago bibliography entry.

The Scribbr Citation Generator is developed using the open-source Citation Style Language (CSL) project and Frank Bennett’s citeproc-js . It’s the same technology used by dozens of other popular citation tools, including Mendeley and Zotero.

You can find all the citation styles and locales used in the Scribbr Citation Generator in our publicly accessible repository on Github .

APA format is widely used by professionals, researchers, and students in the social and behavioral sciences, including fields like education, psychology, and business.

Be sure to check the guidelines of your university or the journal you want to be published in to double-check which style you should be using.

MLA Style  is the second most used citation style (after APA ). It is mainly used by students and researchers in humanities fields such as literature, languages, and philosophy.
