Hello Linux Geeksters. As you may already know, Calibre is an open-source book management software, with many interesting features including e-book conversion, e-book viewer, library to ebook reader synchronization and support for the most popular eBook formats, including: ebup, cbz, mobi, fb2 . Being multiplatform, the app works on Linux, Windows and Mac OS X.
