Spotted this interesting looking free bit of software at jkontherun. This should help me manage by "big" collection of 7 eBooks, things have been getting a bit out of control recently following my big splurge a week or so ago. In all seriousness though it does sound good.
"The software is cross-platform, working on Windows, Mac OS X and Linux. It also supports both Kindle devices, the Sony Reader series, Bookeen’s Cybook and the Apple iPhone/iPod Touch when used with Stanza. Using one or more of the supported devices, Calibre helps to manage e-book collections, but it doesn’t stop there. It can be used to read e-books on a computer, which is handy for when you don’t have a mobile e-book device with you or you want to read content on a larger screen.
Calibre doesn’t stop there though. The software also converts e-book content"
