Introduction FictionBook is an open XML-based e-book format which originated and gained popularity in Russia. FictionBook files have the .fb2 filename extension. The FictionBook format does not specify the appearance of a document; instead, it describes its structure. For example, there are special tags for epigraphs, verses and quotations. Mobipocket SA is a French company incorporated in March 2000 that created the .mobi e-book file format and produces the Mobipocket Reader software for mobile phones, personal digital assistants (PDA) and desktop operating systems.
Technical details In contrast to other eBook formats (e.g. ePub), a FictionBook document consists of a single XML file. Images are converted to Base64 and reside inside the tag, so the size of the embedded images is increased by approximately 37%. FictionBook files are often distributed inside Zip archives. The Mobipocket e-book format is based on the Open eBook standard using XHTML and can include JavaScript and frames. It also supports native SQL queries to be used with embedded databases. The Amazon Kindle's AZW format is basically just the Mobipocket format with a slightly different serial number scheme, and .prc publications can be read directly on the Kindle. The Kindle AZW format also lacks some Mobipocket features such as JavaScript.
