Any device that can display text on a screen may act as an e-reader; however, specialized e-reader devices may optimize portability, readability, and battery life for this purpose. Their main advantage over printed books is portability: an e-reader is capable of storing thousands of books while weighing less than a single one. Another advantage is the convenience provided by add-on features.

Overview

An e-reader is a device designed as a convenient way to read e-books. It is similar in form factor to a tablet computer, but often features electronic paper ("e-ink") rather than an LCD screen. This yields much longer battery life—the battery can last for several weeks—and better readability, similar to that of paper even in sunlight. Drawbacks of this kind of display include a slow refresh rate and (usually) a grayscale-only display, which makes it unsuitable for sophisticated interactive applications such as those found on tablets. This may be perceived as moot or even an advantage, however, inasmuch as the user may simply focus on reading. The Sony Librie, released in 2004 and the precursor to the Sony Reader, was the first e-reader to use electronic paper.

Many e-readers can use the internet through Wi-Fi and the built-in software can provide a link to a digital Open Publication Distribution System (OPDS) library or an e-book retailer, allowing the user to buy, borrow, and receive digital e-books. An e-reader may also download e-books from a computer or read them from a memory card. However, the use of memory cards is decreasing; as the 2010s e-readers lacked a card slot.
