APA citation: book versus electronic book I obtain many of my reading sources from online, instead of form a hardcopy in the library, even for books or book sections. The APA citation requirements for citing printed books and citing e-books are different. If my source IS indeed an e-book, I wonder whether I should really cite e-books according to the e-book citation requirement, which includes URL and all kinds of extra information than citing a printed book. Can I just cite it as if it is from a printed book?
Do not take it for granted that different versions of a book are identical.

Either cite the version you've used, or use the version you want to cite.
