I read a lot, both on paper and on an e-reader, and recently I've been using Calibre to organise and tag my ebooks. Calibre is free and open-source software and I love it! What would be even cooler, though, is having access to my meticulously organised collection on the go, so I could look up novels whose titles are on the tip of my tongue, easily download something new to read on my phone, or send books to friends who would appreciate them when I think of it, instead of waiting till later and probably forgetting. (Where legally appropriate, of course.) That's where the Calibre Content Server comes in.
