calibre vs Cool Reader Comments

- calibre is Free and Open Source
- calibre is Customizable, Lightweight and Privacy focused





































































not a real reader. more a storage, wich duplicate everything you open. And can't use your own book storage.. As reader itself horrible, without simple features.
