From the Purdue Owl Writing Lab Website

These are only some examples. See Purdue website for information about other types of sources.

Book with One Author

Gleick, James. Chaos: Making a New Science. Penguin, 1987.

Henley, Patricia. The Hummingbird House. MacMurray, 1999.

Book with More Than One Author

When a book has multiple authors, order the authors in the same way they are presented in the book. The first given name appears in last name, first name format; subsequent author names appear in first name last name format.

Gillespie, Paula, and Neal Lerner. The Allyn and Bacon Guide to Peer Tutoring. Allyn and Bacon, 2000.

If there are three or more authors, list only the first author followed by the phrase et al. (Latin for "and others") in place of the subsequent authors' names. (Note that there is a period after “al” in “et al.” Also note that there is never a period after the “et” in “et al.”).

Wysocki, Anne Frances, et al. Writing New Media: Theory and Applications for Expanding the Teaching of Composition. Utah State UP, 2004.

Two or More Books by the Same Author

List works alphabetically by title. (Remember to ignore articles like A, An, and The.) Provide the author’s name in last name, first name format for the first entry only. For each subsequent entry by the same author, use three hyphens and a period.

Palmer, William J. Dickens and New Historicism. St. Martin's, 1997.

---. The Films of the Eighties: A Social History. Southern Illinois UP, 1993.

A Page on a Web Site

For an individual page on a Web site, list the author or alias if known, followed by an indication of the specific page or article being referenced. Usually, the title of the page or article appears in a header at the top of the page. Follow this with the information covered above for entire Web sites. If the publisher is the same as the website name, only list it once.

An Article from an Online Database (or Other Electronic Subscription Service)

Cite online databases (e.g. LexisNexis, ProQuest, JSTOR, ScienceDirect) and other subscription services as containers. Thus, provide the title of the database italicized before the DOI or URL. If a DOI is not provided, use the URL instead. Provide the date of access if you wish.

E-mail (including E-mail Interviews)

Give the author of the message, followed by the subject line in quotation marks. State to whom the message was sent with the phrase, “Received by” and the recipient’s name. Include the date the message was sent. Use standard capitalization.

A YouTube Video

Video and audio sources need to be documented using the same basic guidelines for citing print sources in MLA style. Include as much descriptive information as necessary to help readers understand the type and nature of the source you are citing. If the author’s name is the same as the uploader, only cite the author once. If the author is different from the uploader, cite the author’s name before the title.

An Interview

Interviews typically fall into two categories: print or broadcast published and unpublished (personal) interviews, although interviews may also appear in other, similar formats such as in e-mail format or as a Web document.

Personal Interviews

Personal interviews refer to those interviews that you conduct yourself. List the interview by the name of the interviewee. Include the descriptor Personal interview and the date of the interview.

Smith, Jane. Personal interview. 19 May 2014.

Published Interviews (Print or Broadcast)

List the interview by the full name of the interviewee. If the name of the interview is part of a larger work like a book, a television program, or a film series, place the title of the interview in quotation marks. Place the title of the larger work in italics. If the interview appears as an independent title, italicize it. For books, include the author or editor name after the book title.

Note: If the interview from which you quote does not feature a title, add the descriptor, Interview by (unformatted) after the interviewee’s name and before the interviewer’s name.
