Organize, store, and read your e-books
If you own an ebook (electronic book) reader, or just feel like reading books on your desktop or netbook, Calibre will help keep them organized.
Calibre is a library for eBooks. It has a big, bold interface that’s really easy to use, and ebook files of most formats can just be dragged into the Calibre window. Editing the metadata (title, genre etc) is just a case of hitting the button on the tool bar, and typing in your changes. You can select multiple books and edit them in bulk too, for example if you want to regroup some books in a particular genre.
