Calibre 6.4.0


Calibre is an open source e-book library management application that enables you to manage your e-book collection, convert e-books between different formats, synchronize with popular e-book reader devices, and read your e-books with the included viewer.

It acts as an e-library and also allows for format conversion, news feeds to e-book conversion, as well as e-book reader sync features and an integrated e-book viewer.

Calibre's features include: library management; format conversion (all major ebook formats); syncing to e-book reader devices; fetching news from the Web and converting it into ebook form; viewing many different e-book formats, giving you access to your book collection over the internet using just a browser.
