An ebook, also known as an e-book or eBook, is a book publication made available in electronic form, consisting of text, images, or both, readable on the flat-panel display of computers or other electronic devices. Although sometimes defined as "an electronic version of a printed book", some e-books exist without a printed equivalent. E-books can be read on dedicated e-reader devices, also on any computer device that features a controllable viewing screen, including desktop computers, laptops, tablets and smartphones.

A book is a medium for recording information in the form of writing or images. Books are typically composed of many pages, bound together and protected by a cover. Modern bound books were preceded by many other written mediums, such as the codex and the scroll. The book publishing process is the series of steps involved in their creation and dissemination.
