With the wide collection of eBooks now available, it is nice to have a way to keep them organized. It is also nice to have a way to easily read them if you don’t have an eBook reading device. Calibre, a free eBook app, does both!
This free app not only manages your eBooks, it also allows you to create your own categories, apply tags, fetch news, and — one of the most helpful features — convert from one eBook format to another (mobi, ePUB, PDF, and several others).
Calibre is a quality download that makes it easy to read from your laptop, or transfer your files to your Kindle or other eBook-reading device.
