An electronic book (commonly abbreviated e-book) is a text and image-based publication which can be read on a computer or other digital devices such as an e-book reader.
Digital books are well established. Project Gutenberg, an online library of books that can be downloaded free of charge, has been expanding its collection since 1971. Almost its entire library consists of books that are available in the public domain, although there are a few copyright texts which are also included.
The popularity of digital e-books has been accelerated by a number of dedicated portable e-book readers. Amazon Kindle, Sony's eBook readers, and Barnes and Noble nook are extremely popular devices which have enabled readers to conveniently access a huge library of books, magazines and newspapers on the move. What is particularly noteworthy is that Linux is the operating system that runs each of these devices.
However, Linux is also an attractive way of reading e-books on a desktop computer or notebook. Linux has a good range of open source software which helps users to organise their e-book collection, catch up on a novel, or even to create and publish their own e-book.
