Finally, a nice place to archive books you own. Add me if you have one. Still haven't uploaded most of my books, though. So far, about 95% of the ones I've searched for are in their database (which uses Amazon's, I think), though not all editions are present, and some, like some Sandman books I added, display incorrectly on my "shelf," so i had to take them down. Apparently, it's a community site too (and a pretty active one), so you can read reviews and join group discussions on your favorite books. Neat-o!

Thanks to cupkeyk for the link.
