Calibre is an open source e-book management tool. Simply put, calibre allows you to organize your e-book collection, convert e-books to various formats, and interact with your e-book reader, all in an intuitive and friendly manner. It is compatible with Microsoft Windows – XP, Vista, and 7 – as well as Apple’s OS X (and various flavors of Linux). It was created by Kovid Goyal, who still leads its development.
The Calibre Quick Start Guide is distributed with Calibre and freely available on the web; we’re including it here on Weightless with author John Schember’s permission in hopes it will be of help to all the budding micro- and nano-publishers out there.
