Reference List: 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.

Note:  This page reflects the latest version of the APA Publication Manual (i.e., APA 7), which released in October 2019. The equivalent resource for the older APA 6 style  can be found here .

The following rules for handling works by a single author or multiple authors apply to all APA-style references in your reference list, regardless of the type of work (book, article, electronic resource, etc.).

Note:  Because the information on this page pertains to virtually all citations, we've highlighted a few important differences between APA 6 and APA 7 with underlined notes written in red.

Single Author

Last name first, followed by author initials.

Ahmed, S. (2012).  On being included: Racism and diversity in institutional life . Duke University Press.

Two Authors

List by their last names and initials. Separate author names with a comma. Use the ampersand instead of "and."

Soto, C. J., & John, O. P. (2017). The next big five inventory (BFI-2): Developing and assessing a hierarchical model with 15 facets to enhance bandwidth, fidelity, and predictive power. Journal of Personality and Social Psychology , 113 (1), 117-143. http://dx.doi.org/10.1037/pspp0000096

Three to Twenty Authors

List by last names and initials; commas separate author names, while the last author name is preceded again by ampersand.  This is a departure from APA 6, which only required listing the first six authors before an ellipsis and the final author's name.

Nguyen, T., Carnevale, J. J., Scholer, A. A., Miele, D. B., & Fujita, K. (2019). Metamotivational knowledge of the role of high-level and low-level construal in goal-relevant task performance. Journal of Personality and Social Psychology, 117 (5), 879-899. http://dx.doi.org/10.1037/pspa0000166

More Than Twenty Authors

List by last names and initials; commas separate author names. After the first 19 authors’ names, use an ellipsis in place of the remaining author names. Then, end with the final author's name (do not place an ampersand before it). There should be no more than twenty names in the citation in total.

Pegion, K., Kirtman, B. P., Becker, E., Collins, D. C., LaJoie, E., Burgman, R., Bell, R., DelSole, R., Min, D., Zhu, Y., Li, W., Sinsky, E., Guan, H., Gottschalck, J., Metzger, E. J., Barton, N. P., Achuthavarier, D., Marshak, J., Koster, R., . . .  Kim, H. (2019). The subseasonal experiment (SubX): A multimodel subseasonal prediction experiment. Bulletin of the American Meteorological Society , 100 (10), 2043-2061. https://doi.org/10.1175/BAMS-D-18-0270.1

Group Author

Group authors can include corporations, government agencies, organizations, etc; and a group may publish in coordination with individuals. Here, you simply treat the publishing organization the same way you'd treat the author's name and format the rest of the citation as normal. Be sure to give the full name of the group author in your reference list, although abbreviations may be used in your text.

Entries in reference works (  e.g. dictionaries, thesauruses, and encyclopedias) without credited authors are also considered works with group authors.

Merriam-Webster. (2008). Braggadocio. In Merriam-Webster’s Advanced Learner’s English Dictionary . Merriam-Webster.

When a work has multiple layers of group authorship (e.g. The Office of the Historian, which is a part of the Department of State, publishes something), list the most specific agency as the author and the parent agency as the publisher.

Bureau of International Organization Affairs. (2018). U.S. contributions to international organizations, 2017 [Annual report]. U.S. Department of State. https://www.state.gov/u-s-contributions-to-international-organizations/

Unknown Author

When the work does not have an author move the title of the work to the beginning of the references and follow with the date of publication. Only use “Anonymous ” if the author is the work is signed “Anonymous.” This is a new addition to APA 7.

Merriam-Webster's collegiate dictionary (11th ed.). (2003). Merriam-Webster.

NOTE : When your essay includes parenthetical citations of sources with no author named, use a shortened version of the source's title instead of an author's name. Use quotation marks and italics as appropriate. For example, parenthetical citations of the source above would appear as follows: ( Merriam-Webster's , 2003).

Two or More Works by the Same Author

Use the author's name for all entries and list the entries by the year (earliest comes first). List references with no dates before references with dates.

Urcuioli, P. J. (n.d.).

Urcuioli, P. J. (2011). 

Urcuioli, P. J.  (2015).

When an author appears both as a sole author and, in another citation, as the first author of a group, list the one-author entries first.

Agnew, C. R. (Ed.). (2014). Social influences on romantic relationships: Beyond the dyad . Cambridge University Press.

Agnew, C. R., & South, S. C. (Eds.). (2014). Interpersonal relationships and health: Social and clinical psychological mechanisms. Oxford University Press.

References that have the same first author and different second and/or third authors are arranged alphabetically by the last name of the second author, or the last name of the third if the first and second authors are the same.

Arriaga, X. B., Capezza, N. M., Reed, J. T., Wesselman, E. D., & Williams, K. D. (2014). With partners like you, who needs strangers?: Ostracism involving a romantic partner. Personal Relationships, 21(4) , 557-569.

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

If you are using more than one reference by the same author—or the same group of authors listed in the same order—published in the same year, first check to see if they have more specific dates ( this recommendation is new to APA 7) . Works with only a year should be listed before those with a more specific date. List specific dates chronologically.  If two works have the same publication date, organize them in the reference list alphabetically by the title of the article or chapter. If references with the same date are identified as parts of a series (e.g. Part 1 and Part 2), list them in order of their place in the series. Then assign letter suffixes to the year. Refer to these sources in your essay as they appear in your reference list, e.g.: "Berndt (2004a) makes similar claims..."

Berndt, T. J. (2004a).  Children’s friendships: Shifts over a half-century in perspectives on their development and their effects.  Merrill Palmer Quarterly, 50 (3) , 206-223.

Berndt, T. J. (2004b).  Friendship and three A’s (aggression, adjustment, and attachment).  Journal of Experimental Child Psychology, 88 (1) , 1-4.

Introductions, Prefaces, Forewords, and Afterwords

Cite the publishing information about a book as usual, but cite Introduction, Preface, Foreword, or Afterword (whatever title is applicable) as the chapter of the book.

Frequently asked questions

How do i cite a source with multiple authors in mla.

If a source has two authors, name both authors in your MLA in-text citation and Works Cited entry. If there are three or more authors, name only the first author, followed by et al.

Frequently asked questions: MLA Style

In MLA style , footnotes or endnotes can be used to provide additional information that would interrupt the flow of your text.

This can be further examples or developments of ideas you only briefly discuss in the text. You can also use notes to provide additional sources or explain your citation practice.

You don’t have to use any notes at all; only use them to provide relevant information that complements your arguments or helps the reader to understand them.

No, you should use parenthetical MLA in-text citations to cite sources. Footnotes or endnotes can be used to add extra information that doesn’t fit into your main text, but they’re not needed for citations.

If you need to cite a lot of sources at the same point in the text, though, placing these citations in a note can be a good way to avoid cluttering your text.

According to MLA format guidelines, the Works Cited page(s) should look like this:

• Running head containing your surname and the page number.
• The title, Works Cited, centered and in plain text.
• List of sources alphabetized by the author’s surname.
• Left-aligned.
• Double-spaced.
• 1-inch margins.
• Hanging indent applied to all entries.

The MLA Works Cited lists every source that you cited in your paper. Each entry contains the author , title , and publication details of the source.

No, in an MLA annotated bibliography , you can write short phrases instead of full sentences to keep your annotations concise. You can still choose to use full sentences instead, though.

Use full sentences in your annotations if your instructor requires you to, and always use full sentences in the main text of your paper .

If you’re working on a group project and therefore need to list multiple authors for your paper , MLA recommends against including a normal header . Instead, create a separate title page .

On the title page, list each author on a separate line, followed by the other usual information from the header: Instructor, course name and number, and submission date. Then write the title halfway down the page, centered, and start the text of the paper itself on the next page.

Usually, no title page is needed in an MLA paper . A header is generally included at the top of the first page instead. The exceptions are when:

• Your instructor requires one, or
• Your paper is a group project

In those cases, you should use a title page instead of a header, listing the same information but on a separate page.

When an online source (e.g. web page , blog post) doesn’t list a publication date , you should instead list an access date .

Unlike a publication date, this appears at the end of your MLA Works Cited entry, after the URL, e.g. “A Complete Guide to MLA Style.” Scribbr , www.scribbr.com/category/mla/. Accessed 28 Mar. 2021 .

For offline sources with no publication date shown, don’t use an access date—just leave out the date.

The level of detail you provide in a publication date in your Works Cited list depends on the type of source and the information available. Generally, follow the lead of the source—if it gives the full date, give the full date; if it gives just the year, so should you.

Books usually list the year, whereas web pages tend to give a full date. For journal articles , give the year, month and year, or season and year, depending on what information is available. Check our citation examples if you’re unsure about a particular source type.

In an MLA Works Cited list , the names of months with five or more letters are abbreviated to the first three letters, followed by a period. For example, abbreviate Feb., Mar., Apr., but not June, July.

In the main text, month names should never be abbreviated.

In your MLA Works Cited list , dates are always written in day-month-year order, with the month abbreviated if it’s five or more letters long, e.g. 5 Mar. 2018.

In the main text, you’re free to use either day-month-year or month-day-year order, as long as you use one or the other consistently. Don’t abbreviate months in the main text, and use numerals for dates, e.g. 5 March 2018 or March 5, 2018.

In most standard dictionaries , no author is given for either the overall dictionary or the individual entries, so no author should be listed in your MLA citations.

Instead, start your Works Cited entry and your MLA in-text citation with the title of the entry you’re citing (i.e. the word that’s being defined), in quotation marks.

If you cite a specialist dictionary that does list an author and/or overall editor, these should be listed in the same way as they would for other citations of books or book chapters .

Some source types, such as books and journal articles , may contain footnotes (or endnotes) with additional information. The following rules apply when citing information from a note in an MLA in-text citation :

• To cite information from a single numbered note, write “n” after the page number, and then write the note number, e.g. (Smith 105n2)
• To cite information from multiple numbered notes, write “nn” and include a range, e.g. (Smith 77nn1–2)
• To cite information from an unnumbered note, write “un” after the page number, with a space in between, e.g. (Jones 250 un)

If you cite multiple Shakespeare plays throughout your paper, the MLA in-text citation begins with an abbreviated version of the title (as shown here ), e.g. ( Oth. 1.2.4). Each play should have its own  Works Cited entry (even if they all come from the same collection).

If you cite only one Shakespeare play in your paper, you should include a Works Cited entry for that play, and your in-text citations should start with the author’s name , e.g. (Shakespeare 1.1.4).

No, do not use page numbers in your MLA in-text citations of Shakespeare plays . Instead, specify the act, scene, and line numbers of the quoted material, separated by periods, e.g. (Shakespeare 3.2.20–25).

This makes it easier for the reader to find the relevant passage in any edition of the text.

When an article (e.g. in a newspaper ) appears on non-consecutive pages (e.g. starting on page 1 and continuing on page 6), you should use “pp.” in your Works Cited entry, since it’s on multiple pages, but MLA recommends just listing the first page followed by a plus sign, e.g. pp. 1+.

In an MLA style Works Cited entry for a newspaper , you can cite a local newspaper in the same way as you would a national one, except that you may have to add the name of the city in square brackets to clarify what newspaper you mean, e.g. The Gazette [Montreal].

Do not add the city name in brackets if it’s already part of the newspaper’s name, e.g. Dallas Observer .

MLA doesn’t require you to list an author for a TV show . If your citation doesn’t focus on a particular contributor, just start your Works Cited entry with the title of the episode or series, and use this (shortened if necessary) in your MLA in-text citation .

If you focus on a particular contributor (e.g. the writer or director, a particular actor), you can list them in the author position , along with a label identifying their role.

It’s standard to list the podcast’s host in the author position , accompanied by the label “host,” in an MLA Works Cited entry. It’s sometimes more appropriate to use the label “narrator,” when the podcast just tells a story without any guests.

If your citation of the podcast focuses more on the contribution of someone else (e.g. a guest, the producer), they can be listed in the author position instead, with an appropriate label.

MLA recommends citing the original source wherever possible, rather than the source in which it is quoted or reproduced.

If this isn’t possible, cite the secondary source and use “qtd. in” (quoted in) in your MLA in-text citation . For example: (qtd. in Smith 233)

If a source is reproduced in full within another source (e.g. an image within a PowerPoint  or a poem in an article ), give details of the original source first, then include details of the secondary source as a container. For example:

When you want to cite a PowerPoint or lecture notes from a lecture you viewed in person in MLA , check whether they can also be accessed online ; if so, this is the best version to cite, as it allows the reader to access the source.

If the material is not available online, use the details of where and when the presentation took place.

In an MLA song citation , you need to give some sort of container to indicate how you accessed the song. If this is a physical or downloaded album, the Works Cited entry should list the album name, distributor, year, and format.

However, if you listened to the song on a streaming service, you can just list the site as a container, including a URL. In this case, including the album details is optional; you may add this information if it is relevant to your discussion or if it will help the reader access the song.

When citing a song in MLA style , the author is usually the main artist or group that released the song.

However, if your discussion focuses on the contributions of a specific performer, e.g. a guitarist or singer, you may list them as author, even if they are not the main artist. If you’re discussing the lyrics or composition, you may cite the songwriter or composer rather than a performer.

When a source has no title , this part of your MLA reference is replaced with a description of the source, in plain text (no italics or quotation marks, sentence-case capitalization).

Whenever you refer to an image created by someone else in your text, you should include a citation leading the reader to the image you’re discussing.

If you include the image directly in your text as a figure , the details of the source appear in the figure’s caption. If you don’t, just include an MLA in-text citation wherever you mention the image, and an entry in the Works Cited list giving full details.

In MLA Style , you should cite a specific chapter or work within a book in two situations:

• When each of the book’s chapters is written by a different author.
• When the book is a collection of self-contained works (such as poems , plays , or short stories ), even if they are all written by the same author.

If you cite multiple chapters or works from the same book, include a separate Works Cited entry for each chapter.

If a source has no author, start the MLA Works Cited entry with the source title . Use a shortened version of the title in your MLA in-text citation .

If a source has no page numbers, you can use an alternative locator (e.g. a chapter number, or a timestamp for a video or audio source) to identify the relevant passage in your in-text citation. If the source has no numbered divisions, cite only the author’s name (or the title).

If you already named the author or title in your sentence, and there is no locator available, you don’t need a parenthetical citation:

• Rajaram  argues that representations of migration are shaped by “cultural, political, and ideological interests.”
• The homepage of The Correspondent describes it as “a movement for radically different news.”

You must include an MLA in-text citation every time you quote or paraphrase from a source (e.g. a book , movie , website , or article ).

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.

If information about your source is not available, you can either leave it out of the MLA citation or replace it with something else, depending on the type of information.

• No author : Start with the source title.
• No title : Provide a description of the source.
• No date : Provide an access date for online sources; omit for other sources.

A standard MLA Works Cited entry  is structured as follows:

Only include information that is available for and relevant to your source.

Yes. MLA style uses title case, which means that all principal words (nouns, pronouns , verbs, adjectives , adverbs , and some conjunctions ) are capitalized.

This applies to titles of sources as well as the title of, and subheadings in, your paper. Use MLA capitalization style even when the original source title uses different capitalization .

The title of an article is not italicized in MLA style , but placed in quotation marks. This applies to articles from journals , newspapers , websites , or any other publication. Use italics for the title of the source where the article was published. For example:

Use the same formatting in the Works Cited entry and when referring to the article in the text itself.

In MLA style , book titles appear in italics, with all major words capitalized. If there is a subtitle, separate it from the main title with a colon and a space (even if no colon appears in the source). For example:

The format is the same in the Works Cited list and in the text itself. However, when you mention the book title in the text, you don’t have to include the subtitle.

The title of a part of a book—such as a chapter, or a short story or poem in a collection—is not italicized, but instead placed in quotation marks.

In MLA style citations , format a DOI as a link, including “https://doi.org/” at the start and then the unique numerical code of the article.

DOIs are used mainly when citing journal articles in MLA .

The MLA Handbook is currently in its 9th edition , published in 2021.

This quick guide to MLA style  explains the latest guidelines for citing sources and formatting papers according to MLA.

The fastest and most accurate way to create MLA citations is by using Scribbr’s MLA Citation Generator .

Search by book title, page URL, or journal DOI to automatically generate flawless citations, or cite manually using the simple citation forms.

MLA recommends using 12-point Times New Roman , since it’s easy to read and installed on every computer. Other standard fonts such as Arial or Georgia are also acceptable. If in doubt, check with your supervisor which font you should be using.

To create a correctly formatted block quote in Microsoft Word, follow these steps:

• Hit Enter at the beginning and end of the quote.
• Highlight the quote and select the Layout menu.
• On the Indent tab, change the left indent to 0.5″.

Do not put quotation marks around the quote, and make sure to include an MLA in-text citation after the period at the end.

To format a block quote in MLA:

• Introduce the quote with a colon and set it on a new line.
• Indent the whole quote 0.5 inches from the left margin.
• Place the MLA in-text citation after the period at the end of the block quote.

Then continue your text on a new line (not indented).

In MLA style , if you quote more than four lines from a source, use MLA block quote formatting .

If you are quoting poetry , use block quote formatting for any quote longer than three lines.

An MLA in-text citation should always include the author’s last name, either in the introductory text or in parentheses after a quote .

If line numbers or page numbers are included in the original source, add these to the citation.

If you are discussing multiple poems by the same author, make sure to also mention the title of the poem (shortened if necessary). The title goes in quotation marks .

In the list of Works Cited , start with the poet’s name and the poem’s title in quotation marks. The rest of the citation depends on where the poem was published.

If you read the poem in a book or anthology, follow the format of an MLA book chapter citation . If you accessed the poem online, follow the format of an MLA website citation .

Only use line numbers in an MLA in-text citation if the lines are numbered in the original source. If so, write “lines” in the first citation of the poem , and only the numbers in subsequent citations.

If there are no line numbers in the source, you can use page numbers instead. If the poem appears on only one page of a book (or on a website ), don’t include a number in the citation.

To quote poetry in MLA style , introduce the quote and use quotation marks as you would for any other source quotation .

If the quote includes line breaks, mark these using a forward slash with a space on either side. Use two slashes to indicate a stanza break.

If the quote is longer than three lines, set them off from the main text as an MLA block quote . Reproduce the line breaks, punctuation, and formatting of the original.

Referencing multiple authors in Harvard style

Referencing allows you to acknowledge different ideas and materials that you borrow from other authors’ works. Harvard style referencing has two parts:  

• In-text citation – A citation that’s provided in your work (in-text) that indicates where a stated idea or direct quotation comes from.
• Reference list – A list of references that correspond to all in-text citations in the text. Each reference is longer than the in-text citation and contains details like the author’s name, publisher name, year published, place of publication, volumes, and other source information.

Below we will cover how to cite multiple authors in both an in-text citation and a reference.

Two authors are provided

When referencing a source that has two authors, the reference should have the names of both the authors.  

For in-text citations, include the surnames of both authors and the year published.

For references, the surname and first-name initial of each author is listed with “and” between them.  

In-text citation structure:

“Quote” or paraphrase (Surname 1 and Surname 2, Year published)

Surname 1 and Surname 2 (Year published)

In-text citation example:

“Ridley noticed that the ornament from Lena’s graduation had already joined her charm collection” (Garcia and Stohl, 2015).

Garcia and Stohl (2015) noticed that…

Example reference structure (book):

Surname 1, Initial(s). and Surname 2, Initial(s). (Year published) Title in Italics . Place of publication: Name of publisher.

Reference example:

Garcia, K. and Stohl, M. (2015) Dangerous creatures. London: Penguin Books.

Three authors are provided

A reference for a source with three authors will have the names of all three authors. List the authors in the order they are presented in the source (not in alphabetical order).  

For in-text citations, include the surnames of all authors and the year published.

For references, the surname and first-name initial of each author is listed. A comma separates the first and second author names; the word “and” separates the second and third author names.  

“Quote” or paraphrase (Surname 1, Surname 2 and Surname 3, Year published)

Surname 1, Surname 2 and Surname 3 (Year published)

“The parts of the brain are the cerebral hemispheres, the cerebellum, and the brainstem” (Drake, Vogl and Mitchell, 2015).

Surname 1, Initial(s)., Surname 2, Initial(s). and Surname 3, Initial(s). (Year published) Title in Italics . Place of publication: Name of publisher.

Drake, R.L., Vogl, A.W. and Mitchell, A.W.M. (2015) Gray’s anatomy for students . 3 rd rev. edn. Philadelphia, PA: Churchill Livingstone/Elsevier.

Four or more authors are provided

When referencing a source that has four or more authors, use “ et al.” to shorten your list of authors mentioned.  

For in-text citations, use “ et al.” in italics after the surname of the first author. The meaning of “et al.” is ‘and others’. See this guide on when to use et al. in Harvard style for more details.

References can also use “ et al. ” to shorten the list of authors. However, if your institution prefers to have all names listed in a reference, list all the authors by surname and first-name initial. A comma separates the all author names except for the last two names. The word “and” separates the last two author names.  

“Quote” or paraphrase (Surname 1 et al. , Year published)

Surname 1 et al. (Year published)

“Normal ventricular depolarization proceeds as a rapid, continuous spread of activation wave fronts” (Jameson et al., 2018, p. 1676).

Example reference structures (book):

Surname 1, Initial(s). et al . (Year published) Title in Italics . Place of publication: Publisher.

Surname 1, Initial(s)., Surname 2, Initial(s)., Surname 3, Initial(s)., and Surname 4, Initial(s). (Year published) Title in Italics . Place of publication: Name of publisher.

Example references (book):
