Calibre is an open source complete e-library solution. It offers library management, format conversion, news feeds to ebook conversion as well as e-book reader sync features.
Calibre is primarily an e-book cataloging program. It manages your e-book collection for you. It’s designed around the concept of the logical book, i.e. a single entry in the database that may correspond to ebooks in several formats. It also supports conversion from a dozen different e-book formats to LRF and EPUB. A graphical interface to the conversion software can be accessed easily by just clicking the “Convert E-books” button.
Calibre has a modular device driver design that makes adding support for different e-reader devices easy. Syncing supports updating metadata on the device from metadata in the library and the creation of collections on the device based on the tags defined in the library view. If an book has more than one format available, Calibre automatically chooses the best format when uploading to the device.
Calibre can automatically fetch news from a number of websites/RSS feeds, format the news into a e-book and upload to a connected device. There is support for generating LRF/EPUB e-books. The e-books include the *full* versions of the articles, not just the summaries.
Calibre has also a built-in e-book viewer that can display all the major e-book formats.
- Content server – allows you to access your Calibre libraries and read books directly in a browser on your favorite mobile phone or tablet device.
