E-book with author(s): different from print version [from Electronic source using APA 5th ed.]


Some e-books which can be downloaded onto a computer or mobile device have different page numbering from the print version, e.g. e-books from the Project Gutenburg website, Kindle books, Apple iBooks etc. To cite in text, use paragraph numbers (using the abbreviation para.), e.g. para. 582. Alternatively, cite the chapter or section, followed by the paragraph number (if appropriate) e.g. Chapter 4, para. 3).

Whenever possible the internet address (or URL) you give should be a stable URL and link directly to the e-book itself.  To check if a link to a URL is stable, paste the link into the address bar of an Internet browser to make sure that it works. If there is no stable URL for an e-book, give the URL of the website homepage instead.
