How to cite in APA when there are multiple authors

This article covers how to cite a reference in APA style (7th ed.) when there are multiple authors. Broadly speaking, in an APA style “the author” refers to the person(s) or group(s) who should be given credit for the work being referenced.

Here’s a run-through of everything this page includes:

In-text citations when there are multiple authors

Reference list entries when there are multiple authors, troubleshooting.

APA 7th ed. uses the author-date citation system for citing references in text. Unless you are citing a source with no author in APA , the structure in parenthetical citations includes placing the author’s last name/surname, followed by a comma, and the publication year in parentheses. In narrative citations, this information is incorporated into the sentence.

Parenthetical citation for one author:

(Author Last Name, Year Published)

(Curtis, 2020)

Narrative citation for one author:

Author Last Name (Year Published)

Curtis (2020)

Two authors

For a work with two authors, include both authors’ last names in every in-text citation, whether narrative or parenthetical. In parenthetical citations, use an ampersand (&) between the authors’ last names.

Parenthetical citation for two authors:

(1st Author & 2nd Author, Year Published)

(Curtis & Williams, 2020)

Narrative citation for two authors:

1st Author & 2nd Author (Year Published)

Curtis & Williams (2020)

Three or more authors

When citing a journal paper in APA with three or more authors, only enter the last name of the first author listed and add “et al.” after it. “Et al.” is Latin for the phrase “and others,” which is why it is used as a substitute for two or more authors’ last names.

Parenthetical citation for three or more authors:

(1st Author et al., Year Published)

(Harris et al., 2020)

Narrative citation for three or more authors:

1st Author et al. (Year Published)

Harris et al. (2020)

Here is a page with more information on when to use “et al.” in APA style .

Group authors

The same guidelines for in-text citations apply when the authors of a source are a distinct group or organization such as a government agency, association, nonprofit organization, business, hospital, task force, or study group. To confirm whether a reference was written by individual author(s) or a group, check the cover or title page.

Hint: for an online resource, the author could be the name of the organization hosting the webpage or website, rather than the name of just one content contributor.

Before using an abbreviated group name as the author of your citation, spell out the abbreviation and define the group one time first in the text. Afterward, use the abbreviation of the group name throughout the rest of the paper.

Group author in-text citation examples:

First parenthetical citation with group abbreviation included: (Association of Jesuit Colleges and Universities [AJCU], 2020)

Subsequent parenthetical citations: (AJCU, 2020)

First narrative citation with group abbreviation included: The Association of Jesuit Colleges and Universities [AJCU] (2020)

Subsequent narrative citations: The AJCU (2020)

Avoiding ambiguity in in-text citations

Sometimes, in-text citations that have three or more authors, some of whom have the same last name, and the same publication year can look like they are the same reference when using the et al. abbreviation. For example, Curtis et al. (2020) could refer to

Curtis, Acres, Thomas, Henderson, and Tyler (2020)

Curtis, Acres, Thomas, Henderson, Maxey, Key, Smith, and Esparza (2020)

To avoid this ambiguity and confusion for the reader, write out as many names as possible for the in-text citation until the references are distinguished, and then add “et. al” to abbreviate the other authors’ names.

Curtis, Acres, Thomas, Henderson, et al. (2020)

Curtis, Acres, Thomas, Henderson, Maxey, et al. (2020)

When only the final author is different, list all of the names in every citation to avoid any confusion.

Curtis, Acres, Thomas, Henderson, and Esparza (2020)

APA has slightly different reference structures for different source types (e.g., book, website, journal article, etc.), but each structure generally includes the following:

Author last name, Author initials. (Date Published). Title. URL or DOI if available .

Need more help with citing a particular source? Find further guidance in this APA citations guide.

One or two authors

For references with one or two authors, cite using the four-part structure.

Two individual authors example:

Smith, J., & Jones, S. (1994). Making a movie star. Behind the Scenes Stories: A Journal of Celebrity Life, 44 (2), 192–200. https://doi.org/l4nds0r

One group author example:

The American Marine Society. (2003). Whale mating patterns in the new millennium. The American Marine Society Magazine , 17-20 . https://fams.gov/article/2003/whale-mating-patterns-in-the-new-millennium

2 – 20 authors

In APA 7th ed., up to 20 authors should be included in a reference list entry. Write out the last name and first initial(s) for each contributor.

2–20 authors example:

Wright, A., Komal, G., Siddharth, D., Boyd, G., Cayson, N., Beverley, K., Travers, K., Begum, A., Redmond, M., Mills, M., Cherry, D., Finley, B., Fox, M., Ferry, F., Almond, B., Howell, E., Gould, T., Berger, B., Bostock, T., Fountain, A. (2020). Styling royalty. London Bridge Press.

21+ authors

For references with more than 20 authors, after listing the 19th author replace any additional author names with an ellipsis ( … ) followed by the final listed author’s last name and first initial(s).

21+ authors example:

Wright, A., Komal, G., Siddharth, D., Boyd, G., Cayson, N., Beverley, K., Travers, K., Begum, A., Redmond, M., Mills, M., Cherry, D., Finley, B., Fox, M., Ferry, F., Almond, B., Howell, E., Gould, T., Berger, B., Bostock, T., . . . Booker, T. (2020). Eating well: Tips from 23 lifestyle authors. Food Magazine. https://foodmag.com/article/2020/tips-from-22-lifestyle-authors

Solution #1: How to order the names of multiple authors in an APA reference

Authors should be cited in the exact order that they are listed by the source, even if they have not been listed alphabetically.

Solution #2: How to cite an article with more than 20 authors in APA style

If an article has more than 20 authors, all authors do not need to be listed in the reference. Instead, name the first 19, then use an ellipsis (…), then add the name of the final author listed. The ellipsis acts as a substitute for all the names between the first 19 and the final authors. No ampersand (&) is needed before the final name.

For example:

Richards, B.A., Lillicrap, T. P., Beaudoin, P., Bengio, Y., Bogacz, R., Christensen, A., Clopath, C.

Costa, R. P., de Berker, A., Ganguli, S., Gillon, C. J., Hafner, D., Kepecs, A., Kriegeskorte,

N., Latham, P., Lindsay, G. W., Miller, K. D., Naud, R., Pack, C. C., … Kording, K. P. (2019). A deep learning framework for neuroscience. Nature Neuroscience ,  22 (11), 1761–1770. https://doi.org/10.1038/s41593-019-0520-2

When making an in-text citation, only write the first author’s last name followed by “et. al.” This applies to both parenthetical and narrative citations.

(Richard et al., 2019)

Richard et al. (2019)

Solution #3: How to cite an article written by an organization in APA style

• Organization as author

When an article is written by an organization, use the typical four-part APA structure (author, date, title, publisher) and cite the organization as the author.

American Nurses Association. (2019). 2018 Annual Report, American Nurse Today, 14 (6), 29-36.

https://www.nursingworld.org/~49d621/globalassets/docs/ana/ana-annual-report-for-

• Organization as author and publisher

If the organization that authored an article is also its publisher , omit the publisher’s name in the citation.

• In-text citation when an organization is an author

Use the organization’s name as the author. For example:

American Nurses Association [ANA] (2019)

If an organization’s name is long, abbreviate it by doing the following:

• First, write the organization’s name in full the first time, followed by the abbreviation in parenthesis.
• After this, you may use the abbreviation without including the complete name.

1 st in-text narrative citation: American Nurses Association [ANA] (2019)

1 st in-text parenthetical citation: (American Nurses Association [ANA] (2019)

After this distinction is made, abbreviations in-text can be used as demonstrated below:

Narrative citations: The ANA (2019)

Parenthetical citations: (ANA, 2019)

To cite a source with multiple authors and an edition number in APA style, you need to know the names of the authors, title of the book, edition number, and publisher. The in-text citation of a book with multiple authors and an edition number is similar to citing a journal or a book reference with multiple authors. An example of a book reference with three authors and an edition number, along with a template, is given below:

In-text citation template and example:

Author Surname et al. (Publication Year)

LeBuffe et al. (2012)

Parenthetical

(Author Surname et al., Publication Year)

(LeBuffe et al., 2012)

Reference list entry template and example:

Author Surname, F. M., Author Surname, F. M., & Author Surname, F. M. (Publication Year). Book title (edition number). Publisher

LeBuffe, P. A., Naglieri, J. A., & Manderth, A. (2012). Devereux early childhood assessment for preschoolers (2nd ed.). Kaplan Early Learning Company.

Use numerals to indicate an edition number. The word “edition” is abbreviated as “ed.” Italicize the book title and follow sentence case for capitalization.

Citing a source that has multiple authors with the same last name and same initials is the same as citing a source with different authors. There is no need to add the initials of the authors in in-text citations as all surnames (although the same) appear in a single source. Examples of a book reference with three authors with the same last name and initials and their templates are given below:

Dunn et al. (2007)

(Dunn et al., 2007)

Author Surname, F. & Author Surname, F. (Publication Year). Book title. Publisher.

In-Text Citations: Author/Authors

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

Though the APA's author-date system for citations is fairly straightforward, author categories can vary significantly from the standard "one author, one source" configuration. There are also additional rules for citing authors of indirect sources, electronic sources, and sources without page numbers.

A Work by One Author 

The APA manual recommends the use of the author-date citation structure for in-text citation references. This structure requires that any in-text citation (i.e., within the body of the text) be accompanied by a corresponding reference list entry. In the in-text citation provide the surname of the author but do not include suffixes such as "Jr.". 

Citing Non-Standard Author Categories

A work by two authors.

Name both authors in the signal phrase or in parentheses each time you cite the work. Use the word "and" between the authors' names within the text and use the ampersand in parentheses.

A Work by Three or More Authors

List only the first author’s name followed by “et al.” in every citation, even the first, unless doing so would create ambiguity between different sources.

In  et al. , et  should not be followed by a period. Only "al" should be followed by a period.

If you’re citing multiple works with similar groups of authors, and the shortened “et al” citation form of each source would be the same, you’ll need to avoid ambiguity by writing out more names. If you cited works with these authors:

They would be cited in-text as follows to avoid ambiguity:

Since et al. is plural, it should always be a substitute for more than one name. In the case that et al. would stand in for just one author, write the author’s name instead.

Unknown Author

If the work does not have an author, cite the source by its title in the signal phrase or use the first word or two in the parentheses. Titles of books and reports are italicized; titles of articles, chapters, and web pages are in quotation marks. APA style calls for capitalizing important words in titles when they are written in the text (but not when they are written in reference lists).

Note : In the rare case that "Anonymous" is used for the author, treat it as the author's name (Anonymous, 2001). In the reference list, use the name Anonymous as the author.

Organization as an Author

If the author is an organization or a government agency, mention the organization in the signal phrase or in the parenthetical citation the first time you cite the source, just as you would an individual person.

If the organization has a well-known abbreviation, you may include the abbreviation in brackets the first time the source is cited and then use only the abbreviation in later citations. However, if you cite work from multiple organizations whose abbreviations are the same, do not use abbreviations (to avoid ambiguity).

Two or More Works in the Same Parentheses

When your parenthetical citation includes two or more works, order them the same way they appear in the reference list (viz., alphabetically), separated by a semi-colon.

If you cite multiple works by the same author in the same parenthetical citation, give the author’s name only once and follow with dates. No date citations go first, then years, then in-press citations.

Authors with the Same Last Name

To prevent confusion, use first initials with the last names.

Two or More Works by the Same Author in the Same Year

If you have two sources by the same author in the same year, use lower-case letters (a, b, c) with the year to order the entries in the reference list. Use the lower-case letters with the year in the in-text citation.

Introductions, Prefaces, Forewords, and Afterwords

When citing an Introduction, Preface, Foreword, or Afterword in-text, cite the appropriate author and year as usual.

Personal Communication

For interviews, letters, e-mails, and other person-to-person communication, cite the communicator's name, the fact that it was personal communication, and the date of the communication. Do not include personal communication in the reference list.

If using a footnote to reference personal communication, handle citations the same way.

Traditional Knowledge of Indigenous Peoples

When citing information you learned from a conversation with an Indigenous person who was not your research participant, use a variation of the personal communication citation above. Include the person’s full name, nation or Indigenous group, location, and any other relevant details before the “personal communication, date” part of the citation.

Citing Indirect Sources

Generally, writers should endeavor to read primary sources (original sources) and cite those rather than secondary sources (works that report on original sources). Sometimes, however, this is impossible. If you use a source that was cited in another source, name the original source in your signal phrase. List the secondary source in your reference list and include the secondary source in the parentheses. If you know the year of the original source, include it in the citation.

Electronic Sources

If possible, cite an electronic document the same as any other document by using the author-date style.

Unknown Author and Unknown Date

If no author or date is given, use the title in your signal phrase or the first word or two of the title in the parentheses and use the abbreviation "n.d." (for "no date").

Sources Without Page Numbers

When an electronic source lacks page numbers, you should try to include information that will help readers find the passage being cited. Use the heading or section name, an abbreviated heading or section name, a paragraph number (para. 1), or a combination of these.

Note:  Never use the page numbers of webpages you print out; different computers print webpages with different pagination. Do not use Kindle location numbers; instead, use the page number (available in many Kindle books) or the method above. 

Other Sources

The  APA Publication Manual  describes how to cite many different kinds of authors and content creators. However, you may occasionally encounter a source or author category that the manual does not describe, making the best way to proceed unclear.

In these cases, it's typically acceptable to apply the general principles of APA citation to the new kind of source in a way that's consistent and sensible. A good way to do this is to simply use the standard APA directions for a type of source that resembles the source you want to cite. For example, a sensible way to cite a virtual reality program would be to mimic the APA's guidelines for computer software.

You may also want to investigate whether a third-party organization has provided directions for how to cite this kind of source.

APA 7th Edition Citation Guide Multiple Authors

Source with two authors.

Rules for citing more than one author apply to all sources, regardless of format. Below is an example of a book with two authors.

Use the word "and" between the authors' names within the text and use an ampersand (&) for parenthetical citations.

Reference Page Format:

Author, A. A., & Author, B. B. (Year of Publication). Format the remainder according to resource type.

Reference Page Example:

Loveless, D., & Griffith, B. (2014).  Critical pedagogy for a polymodal world . Birkhäuser.

In-text Citation Examples:

According to Loveless and Griffith (2014) ... ...(Loveless & Griffith, 2014). ...(Loveless & Griffith, 2014, p. 121).

Source with Three to Twenty Authors

For all sources with three to twenty authors, include all of the authors on your References page. 

For in-text citations, sources with three or more authors can be abbreviated to only the first author's last name followed by "et al." For example, (Author et al., Year).

Author, A. A., Author, B. B., Author, C. C. (Year of Publication).  Format the remainder according to resource type .

According to Somerville et al. (2011) ... ... (Somerville et al., 2011). ... (Somerville et al., 2011, p. 549).

Source with Twenty-One or More Authors

For sources with twenty-one or more authors, write out the first twenty authors on the References page, add an ellipsis (...), and end with the last author. 

For in-text citations, sources with more than twenty authors can be abbreviated to only the first author's last name followed by "et al." For example, (Author et al., Year).

Author, A. A., Author, B. B., Author, C. C., Author, D. D., Author, E. E., Author, F. F., Author, G. G., Author, H. H., Author, I. I., Author, J. J., Author, K. K., Author, L. L., Author, M.

Digital Object Identifier (DOI)

What is a DOI? A DOI ( digital object identifier ) is a unique alphanumeric string assigned by a registration agency (the International DOI Foundation) to identify content and provide a persistent link to its location on the internet. 

NOTE: It is regarded as the most important part of the citation because it will accurately direct users to the specific article.

Think of it as a "digital fingerprint" or an article's DNA!

The rules for DOIs have been updated in the 7th edition of the Publication Manual of the American Psychological Association. They should be included as URLs, rather than just the alphanumeric string.

Correct:  

• http://doi.org/10.1186/1471-2288-12-114
• http://dx.doi.org/10.1186/1471-2288-12-114

Incorrect:

Journal Article with Three to Twenty Authors

Helpful Tips:

DOI: If a journal article has a Digital Object Identifier (DOI) listed, you will always include this identifier in your reference as a URL.

Online Database: For works from databases that publish works of limited circulation (such as the ERIC database) or original, proprietary material available only in that database (such as UpToDate), include the name of the database or archive and the URL of the work. If the URL requires a login or is session specific, meaning it will not resolve for readers, provide the URL of the database or specific archive home page or login page instead of the URL for the work.

Print: If you viewed a journal article in its print format , be sure to check if it has a DOI listed. If it does not, your reference to the article would end after you provide the page range of the article.

Date: When possible, include the year, month, and date in references. If the month and date are not available, use the year of publication.

Surnames and initials for  up to twenty authors  should be provided in the reference list.  For more than 20 authors, list the first 19, followed by an ellipsis, then list the final author.

In-Text Citation (Paraphrase):

Citing multiple authors in APA style

Published October 27, 2020. Updated August 25, 2021.

You will often encounter sources that have more than one individual author. For example, many academic journal articles have several authors.

For help writing your essay, research paper , or other project, check out these writing tips .

Citing two authors in APA

When referencing a source with two authors, the names of both authors are included in the both the in-text citation and reference list entry.

In-text citation template and examples:

(First author’s last name & Second author’s last name, Year published)

The discovery of the effect of radiation on the climate was astonishing (Smith & Montez, 2011).

Smith and Montez (2011) discovered the astonishing effect of radiation on the climate.

Reference list template and example (book):

First author’s last name, F., & Second author’s last name, F. (Year published). Title of the book. Publisher. DOI if available

Swan, A., & Stevens, N. (2004). De Kooning: An American master. Alfred A. Knopf.

Citing three to twenty authors in APA

For sources that have three to 20 authors, list only the last name of the first listed author in the in-text citation followed by “et al.” “Et al.” means “and others.”

Citation template and examples:

(First author’s last name et al., Year published)

(Jameson et al., 2018)

Jameson et al. (2018)

The reference list entry will still list all of the names of the authors in the last name, first initial format. The last author name should be preceded by an ampersand (&).

Reference list template (journal article):

First author’s last name, F., Next author’s last name, F., Next author’s last name, F., & Last author’s last name, F. (Year of publication). Title of the article: Subtitle of the article. Title of the journal, Volume (issue number) , page range. DOI or URL

American Journal of Psychiatry, 158 (11), 179. https://doi.org/10.1176/appi.ajp.2020.20071051

Citing twenty-one or more authors in APA

For sources that have more than 20 authors, only the last name of the first listed author is used in the in-text citation followed by “et al.”

(Sakamoto et al., 2018)

In the reference list, the names of the first 19 authors are included, followed by a comma and ellipsis, and then the name of the last author (also formatted as last name, first initial).

Reference template (journal article):

Names of the first 19 authors formatted as Last Name, F., . . . Last author’s last name, F. (Year of publication). Title of the article: Subtitle of the article. Title of the Journal, Volume (issue number), page range. DOI or URL

How to Cite Multiple Authors in APA style

• 3-minute read
• 18th June 2023

According to the Guinness Book of World Records , the highest number of authors to work on a single peer-reviewed academic paper is 15,025. While you may not ever encounter a source with that many authors during your own research , you’ll probably come across works with more than one author.

In this post, we’ll show you how to cite multiple authors in APA style, both in the text and on the reference page.

Creating a Reference List Entry for Two Authors

To write a reference list entry for a work with two authors, follow this basic format when listing the authors:

List the authors by their last names and initials, and use a comma followed by an ampersand to separate the two names. Here’s an example of what this might look like for a book entry:

Citing 3–20 Authors on a Reference Page

APA 7 differs from APA 6 on how to cite 3–20 authors on a reference page. APA 6 requires listing up to six names in full, followed by an ellipsis and the final author’s name. APA 7 requires that you list all the authors’ names, with an ampersand separating the last two. Follow this basic format for up to 20 authors in APA 7:

Here’s what this might look like for a book on the reference page:

Citing More than 20 Authors on a Reference Page

In APA 7, if a work contains 21 or more authors, list the surnames and initials of the first 19, followed by a comma, an ellipsis, and the name of the final author. Follow this basic format:

Note that you should not use an ampersand in this scenario, only an ellipsis.

How to Cite Multiple Authors in the Text

When writing a narrative citation for a work with two authors, use “and” between the authors’ names rather than an ampersand. Immediately follow the authors’ names with the year of publication in parentheses. For example:

However, for a parenthetical citation , use an ampersand between the authors’ names, followed immediately by a comma and the year of publication. For example:

When citing a work with three or more authors, include the first named author, followed by “et al.” and the year of publication. In a narrative citation, this will look like:

And here’s an example of this in a parenthetical citation:

For direct quotations, you should also include the page number(s) along with the names and year.
