Ebooks

Broadly, ebooks are electronic versions of books. Ebooks can be simple Web-based representations of books (via HTML, CSS and other Web-markup technologies) or they can be ported into more advanced file formats that bring the traditional "book" look and feel into the digital domain.

Many ebooks are defined by their file formats. Some formats can only be read on specific devices (e.g. AZW ebooks only render on Amazon's Kindle e-reader), while other formats can be read across different equipment and software platforms (e.g. EPUB and PDF).
