About the formats

Extension fb2
Category E-book file formats
Developed by Dmitry Gribov
Mime type application/x-fictionbook+xml

Description

FB2 is short for the FictionBook 2 format for e-books, created by the Russian Dmitry Gribov. It is XML-based, meaning it describes the structure of the book or document, instead of its styles and appearance. This file format is completely DRM-free. It also has support for some inline formatting.
Extension mobi
Category E-book file formats
Developed by Mobipocket, now Amazon
Mime type application/x-mobipocket-ebook

Description

MOBI is a Mobipocket e-book file. Even though it was originally made for the Mobipocker Reader for PDAs (now defunct), it is supported by other e-book readers. MOBI is specifically designed for low-bandwidth mobile devices. In addition to storing the contents of digital books, MOBI files may include bookmarks and DRM protection. The latter prevents creating unauthorized copies of the book and acts as copyright protection.
