While you wait for the download to complete, please consider contributing to support the development of calibre.

Previous releases of calibre are available here.

Note

64bit calibre can be installed at the same time as 32bit calibre. The two calibre installs will use the same book library, plugins and settings.

If you are using Windows XP please, use calibre 1.48, which works with all Windows XP machines, from here. Simply un-install calibre and install 1.48, doing so will not affect your books/settings.
