calibre is a free and open source e-book library management application developed by users of e-books for users of e-books.
Lots has changed in calibre-land in the last year. A great feature is "Get Books" which allows you to search for a book by title and author and returns the list of web stores that sell it in ebook form, allowing you to easily find the lowest prices for popular books or search many different places for hard to find ebook editions.
The last year has also seen the maturing of the calibre plugin infrastructure, which has led to a vibrant community of user developed plugins that extend calibre's functionality in many novel ways. See the Index of plugins.
calibre has an all new metadata download system that allows you much more control over the process. For example, you can now choose a cover from many different online sources.
As always, calibre has gained support for dozens of new devices, conversion of a few new formats, notably, SNB and the Plucker formats. The performance of calibre has been greatly improved, especially with large libraries of tens of thousands of books.
While not directly calibre related, a new website that catalogues unrestricted access ebooks for sale was started: Open Books. All the books on this website are for sale, but they do not have DRM, which means you actually own them after paying for them. You can convert them to different formats, fix typos in them, view them on as many devices as you like. At calibre, we believe that DRM free is the future of digital information and Open Books is a small effort to help speed that future along.
These and many more new features are described in detail below.
