There's little in the way of quality freeware applications which can create a library and provide a reader for e-books. That all changes with calibre, a free and open source library management and conversion utility for e-book collections.
Calibre is a free e-book manager which can be compared to a program like iTunes, but for e-books. It can connect to your reader device and can convert between various different e-book formats.
Along with the ability to convert between popular formats, calibre can also popular your library and sorts them neatly.
Overall, this is an excellent all-round e-book tool which provides many of the functions which are requested by users of different devices.Features and highlights
