How to Cite an eBook

  • Ebooks need some extra information in their citations, just as e-articles do.
  • RefWorks will pull citations from the library catalog or article database, but you must still add the extra information to show that you used an electronic source

AMA (American Medical Association)

APA Style

APA = American Psychological Association

Note that APA style requires you to add the type of e-device, where you retrieved the ebook, and the URL or doi.

  • Gladwell, M. (2008). Outliers: The story of success [Kindle DX version]. Retrieved from
  • Shotton, M.A. (1989) Computer addiction? A study of computer dependency [DX Reader version]. Retrieved from]
  • Brill, P. (2004). The winner’s way [Adobe Digital Editions version]. doi:10.1036/007142363X

Here is more information about APA style, including the APA Style Blog, which you can search for more information about citing electronic things.

    MLA = Modern Language Association

    The MLA understands that the world of citing electronic information is fluid (phone call, April 21, 2011).

    Usually, you can use the style for citing a print book and then just add the additional information to indicate its electronic origin and when you accessed it, as shown below.

    The point to remember is to include enough information for others to be able to find your source.

    • Author or Editor’s Last Name, First Name. Title of Book [put in quotes if part of a book]. Title of the Website. Editor of website [if given]. Publisher or sponsor of site [or N.p. if not available], Date of electronic publication [or N.d. if not available]. Medium [e.g., Web]. Day Month year of access.
