Calibre is a free, open-source program (written in Python) for managing e-book libraries on Windows, Mac and Linux. It offers the most rich set of features, divided into the following main categories: library management, e-book conversion, synchronization with e-readers, downloading news from the internet and converting them to e-book formats, e-book viewer-reader, e-book editor and a content server for web access to your book collection. The program reorganizes book files into own structure. There are numerous plugins developed for the program by the community. However, many find the interface cluttered and unwieldy.
