The Kingdom Come

Perhaps the best free software I've found for helping to manage or organize your ebooks is an open source program called Calibre. Calibre was created by Kovid Goyal in 2006 and has ever-since been developed by a team of open source enthusiasts.

Although Calibre is a combination of the word libre, meaning freedom, thus indicating its free open-source nature, Goyal suggests it be pronounced Cali-ber.
