Calibre for Mac v4.8.0

Calibre is a free and open source e-book library management application developed by users of e-books for users of e-books. It has a cornucopia of features divided into the following main categories:

Library Management
E-book conversion
Syncing to e-book reader devices
Downloading news from the web and converting it into e-book form
Comprehensive e-book viewer
Content server for online access to your book collection
E-book editor for the major e-book formats

Calibre started life on 31 October, 2006, soon after the release of the SONY PRS-500, the first e-ink based reader to be sold commercially in the US. At the time, I was a graduate student, with a lot of time on my hands. The PRS-500 did not work at all with Linux, my operating system of choice, so I decided to reverse engineer the USB protocol that it used, to get it working on Linux. This was accomplished with the help of the fine folks over at mobileread.com and calibre was born, albeit named libprs500.

At the time there were no satisfactory tools to convert content into the LRF format, used by the SONY reader, so I decided to implement a converter to convert the most popular e-book formats to LRF. This converter proved to be wildly popular and far better than the (mostly non-existent) offerings from SONY. It was picked up and used by various publishing houses and content digitizers to produce the first generation of books in the LRF format.

As my e-book collection grew, I realized that managing it was quickly becoming unwieldy, so I decided to write a graphical interface to libprs500 to make it easier. This became calibre, in its present form, as a comprehensive e-book management tool. libprs500 was renamed to calibre in mid-2008. The name calibre was chosen by my wife, Krittika. The libre in calibre stands for freedom, indicating that calibre is a free and open source product, modifiable by all. Nonetheless, calibre should be pronounced as cali-ber, not ca-libre.

Today calibre is a vibrant open-source community with half a dozen developers and many, many testers and bug reporters. It is used in over 200 countries and has been translated into a dozen different languages by volunteers. calibre has become a comprehensive tool for the management of digital texts, allowing you to do whatever you could possibly imagine with your e-book library. Reading is very important to me and one of my goals has always been to prevent either the fragmentation or the monopolization of the e-book market by entities that care solely for short-term goals. As the calibre community continues to grow, driven by book lovers, for book lovers, hopefully it will always present an alternative for people that love to read e-books and want to be in control of their own digital libraries.
