The Modern Language Association establishes that the basic format to cite e-books is similar to the printed versions; except for adding the medium of publication.
Consequently, the reference of an e-book will look like:
Surname, First name. Title. Place of publication (if known): Publisher, year. Database. Medium of publication. Date it was accessed (DD MM YYYY)
An example of how an ebook should be cited according to the MLA style is the following:
Edgell, S. The Sociology of Work: Continuity and Change in Paid and Unpaid Work. Thousand Oaks: Sage, 2011. eBooks.com. Web. 15 February 2013
If the book is on an e-reader, the type of file should also be included and the reference will look like:
Leo, K., Hoggett, J. and Sweeting, J. Company Accounting. 9th ed. Australia: John Wiley & Sons, 2012. Google ebook.
