E-Book, fiction or nonfiction text that is distributed and read in digital form, usually on a computer or handheld display device. Because they can be cheaply distributed worldwide over the Internet and do not require shelf space, e-books have the potential to someday replace the printed book. Devices that store and display electronic texts are sometimes referred to generically as e-books.
E-book texts are downloaded to a computer or a reading device through a modem or other Internet connection. Some devices cannot download texts and must be connected to another computer in order to transfer the book to its memory. Once a book is downloaded, the computer or e-book device uses special software to display the text for reading. Most e-book devices run on batteries so they can be taken anywhere, like a printed book. The text is displayed on a backlit screen for easier reading. Controls allow the reader to scroll up and down and to move forward and back in the text. Depending on battery technology and screen features, some devices can provide 40 or more hours of reading time before recharging.
E-books and e-book devices have several advantages over traditional printed books. E-book devices can hold the texts of many different books at one time, making them popular with students or professionals who have to carry or consult many reference materials, technical manuals, or textbooks. Many devices also allow the reader to select from various type sizes, search the text, switch quickly between books, and access stored reference works to look up unfamiliar words or concepts. Because they lack the high costs of printing and distribution, e-books also have the potential to yield greater profits for publishers and authors. In addition, more and more first-time authors or those who write on lesser-known topics have turned to e-books to get their books published.
E-books also have potential disadvantages, some of which might be addressed as technology improves. These include the cost of the computer or e-book device, consumer resistance to reading on electronic screens, and uncertainty about the business model. Concerns about pricing, royalties, illegal copying of texts, and the lack of a single software standard for publishing e-books have slowed the rollout of e-books by major publishing companies.
