FBReader

FBReader is an e-book reader for Linux, Microsoft Windows, Android, and other platforms.

It was originally written for the Sharp Zaurus and currently runs on many other mobile devices, like the Nokia Internet Tablets, as well as desktop computers. A preview of FBReaderJ (the Java port) for Google Android was released on April 13, 2008.

Supported formats include EPUB, FictionBook, HTML, plucker, PalmDoc, zTxt, TCR, CHM, RTF, OEB, mobi without DRM, and plain-text.

It was formerly free software under the GPL, but since 2015 (v2.7) is proprietary software.

History
Nikolay Pultsin wrote the first FBReader; the tool was released for the Sharp Zaurus in January 2005, a Maemo port was added in December 2005 for the Nokia 770. FBReader has since had binary packages released for many mobile-device platforms and for most major personal computer operating systems. The FBReader name with the FB prefix comes from FictionBook, an e-book format popular in Russia, the country of FBReader's author.

The original FBReader was written in C++; however, in 2007 a fork called FBReaderJ was created, which was written in Java. As the Android platform became available in the following years, this fork became the codebase for the Android software application, while the C++ codebase remained in use for other platforms.

In 2015 the software for all platforms became closed-source: the old open-source code hasn't been updated since. The Android app was split into Free and Premium versions, both closed-source, with the Premium version adding integrated support for PDF and for machine translation.

Components
For easy cross-platform compiling, FBReader uses zlibrary, a cross-platform interface library. It allows recompiling for many platforms while disregarding the GUI-toolkit used.
