Fellow bookworms, this may be of interest: LibraryThing.
One of those ideas so simple you'll wonder why you didn't think of it yourself, and so wonderful you'll just be grateful that someone else did anyway.
It is my newest (and possibly dorkiest) obsession. The first night, I stayed up until four in the morning in a desperate attempt to catalog every single book I owned. Then I had to trawl the web to find exact front cover matches. Then the inconsistent format of the publishers' details began to bug me so I started to edit them individually - still not done. But it's fun! Good dorky fun!
