Ebook

An ebook (short for electronic book), also spelled as 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.

In the 2000s, there was a trend of print and e-book sales moving to the Internet, where readers buy traditional paper books and e-books on websites using e-commerce systems. With print books, readers are increasingly browsing through images of the covers of books on publisher or bookstore websites and selecting and ordering titles online. The paper books are then delivered to the reader by mail or any other delivery service. With e-books, users can browse through titles online, select and order titles, then the e-book can be sent to them online or the user can download the e-book. By the early 2010s, e-books had begun to overtake hardcover by overall publication figures in the U.S.

The main reasons people buy e-books are possibly because of lower prices, increased comfort (as they can buy from home or on the go with mobile devices) and a larger selection of titles. With e-books, "electronic bookmarks make referencing easier, and e-book readers may allow the user to annotate pages." "Although fiction and non-fiction books come in e-book formats, technical material is especially suited for e-book delivery because it can be digitally searched" for keywords. In addition, for programming books, code examples can be copied. In the U.S., the amount of e-book reading is increasing. By 2021, 30% of adults had read an e-book in the past year, compared to 17% in 2011. By 2014, 50% of American adults had an e-reader or a tablet, compared to 30% owning such devices in 2013.

Besides published books and magazines that have a digital equivalent, there are also digital textbooks that are intended to serve as the text for a class and help in technology-based education.

E-books are also referred to as "ebooks", "e-books", "eBooks", "Ebooks", "e-Books", "e-journals", "e-editions", or "digital books". A device that is designed specifically for reading e-books is called an "e-reader", "ebook device", or "eReader".

Some trace the concept of an e-reader, a device that would enable the user to view books on a screen, to a 1930 manifesto by Bob Brown, written after watching his first "talkie" (movie with sound). He titled it The Readies, playing off the idea of the "talkie". In his book, Brown says movies have outmaneuvered the book by creating the "talkies" and, as a result, reading should find a new medium:

A simple reading machine which I can carry or move around, attach to any old electric light plug and read hundred-thousand-word novels in 10 minutes if I want to, and I want to.

Brown's notion, however, was much more focused on reforming orthography and vocabulary, than on medium. He says: "It is time to pull out the stopper" and begin "a bloody revolution of the word," introducing huge numbers of portmanteau symbols to replace normal words, and punctuation to simulate action or movement, so it is not clear whether this fits into the history of "e-books" or not. Later e-readers never followed a model at all like Brown's. However, he correctly predicted the miniaturization and portability of e-readers. In an article, Jennifer Schuessler writes: "The machine, Brown argued, would allow readers to adjust the type size, avoid paper cuts and save trees, all while hastening the day when words could be 'recorded directly on the palpitating ether.'" Brown believed that the e-reader (and his notions for changing the text itself) would bring a completely new life to reading. Schuessler correlates it with a DJ spinning bits of old songs to create a beat or an entirely new song, as opposed to just a remix of a familiar song.
