Calibre – An Ebook Management System

Maintaining large collections of Ebooks can become a nightmare, if not maintained properly finding the desired books is also a difficult job. Calibre is a one word solution to this problem. calibre is free and open source e-book software that organizes and manages e-books, supporting a variety of formats. It also supports e-book syncing with a variety of popular e-book readers and will convert e-books between differing formats.

Calibre helps you catalog your e-book collection. First, it surveys all the e-books and other relevant files residing either on your hard drive or your e-reader, and then inserts them into Calibre’s main directory. Once that information is in the directory, you can use it to organise, categorize, annotate, search, rate and save to disk. You can customize or delete any of the data fields Calibre fills in, or add your own.

Its main features are :
