An electronic book (also e-book, ebook, digital book) is a text- and image-based publication in digital form produced on, published by, and readable on computers or other digital devices. E-books are presented visually or aurally, with the *audio book as a precursor to, and limited exemplum of, electronic publishing's potential. Components other than text have been considered enhancements, including multimedia (sound, images, film/video/animated graphics).
