(Electronic-BOOK) The electronic counterpart of a printed book, which can be viewed on a desktop computer, laptop, smartphone, tablet or e-book reader (e-reader). When traveling, a huge number of e-books can be stored in portable units, dramatically eliminating weight and volume compared to paper. 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 searched. In addition, programming code examples can be copied, which is why CD-ROMs that contained examples or the entire text were often packaged inside technical paper books.

E-Book Formats
There are several e-book formats on the market, including EPUB, Mobipocket (PRC, MOBI), eReader (PDB), Kindle (AZW, KF8) and Apple iBook (EPUB variation). Many e-readers also accept generic formats, including Adobe PDF and plain text (TXT).

Amazon's Kindle and Apple's iPad
In 2007, Amazon.com revolutionized the market. The Kindle was the first e-reader with free cellular access to download e-books (see Kindle). In 2010, Apple introduced the iPad tablet, featuring downloadable "iBooks" (see iPad). See PDF, EPUB, Open eBook and Mobipocket.
