An electronic version of a book. Types of e-book products available include the Rocket eBook, from Nuvomedia (www.nuvomedia.com) and the SoftBook from SoftBook Press (www.softbook.com). Both are small computers -- the size of a paperback and a legal notepad -- with
backlighted screens that allow a user to read, save, highlight, bookmark, and annotate text. Both can download books from a
Web site, such as barnesandnoble.com (although the Rocket eBook requires another PC).
