Library Thing

I've already used Library thing before. But instead of using it to document what books I have at home, I use it to list books that I've read or heard about and want to read in the future. That way if I'm out and have access to the internet I can check what titles I want (saves me carrying around a tatty piece of paper) http://www.librarything.com/catalog.php I don't know if this link will work. Looks pretty generic to me.
