An e-book (short for electronic book, also written eBook or ebook) is an e-text that forms the digital media equivalent of a conventional printed book, sometimes protected with a digital rights management system. E-books are usually read on personal computers or smart phones, or on dedicated hardware devices known as e-book readers or e-book devices. Many mobile phones can also be used to read e-books.

I'd like to express my appreciation to my colleague Christopher D. Rumbaugh, Adult Services Reference Librarian at the Corvallis-Benton County Public Library
in Corvallis Oregon, who created the structure upon which this guide is based, and identified many of the resources that it contains.
