FBReader

FBReader is a platform (available for Linux, Windows and FreeBSD) e-book readers, compatible with many manufacturers (Sharp, Nokia, Siemens or Motorola) mobile devices.

The long list of formats supported by FBRaidar is fb2, HTML, CHM, placquer, palmoose, zdiste, TCR, RTF, orbie and opibrador.

Point to the folder containing your e-books. FBReader will then detect all integrated ebooks, even when they are stored in a compressed file (TAR, GZIP, ZIP or BZIP2).

Below the FBReader's interface there is a guide that shows you an image embedded in a book that is part of the book, helps you with footnotes and hyperlinks and can turn the document.
