Kindle may be the # 1 platform to build your e-book collection.

But what if you have plenty of PDF, ePub and mobi books lying around in your devices? Downloaded from Gutenberg or by signing up for your favourite mailing list?

Are you tired of switching from device to device to read different material? Isn't it annoying that the highlights you created inside a book on one device aren't available on another device?

Enter Calibre.
