When it comes to citing, a book read on a Nook or Kindle is very similar to a book read in print. For MLA, an e-book is considered a version of a book, so it should be listed after the title and before the publication information.
For MLA, the citation would look like this:
Grisham, John. The Pelican Brief. Kindle ed., Dell, 1992.
*NOTE: If you are unsure of the file type, then use the generic "Digital file" instead.
For APA, the citation would look like this:
Grisham, J. (1992). The Pelican Brief [Kindle Fire version]. Retrieved from Amazon.com.
