LibraryThing
Ever wanted to keep track of all your books? Every wondered who out there has similar tastes in reading material? Ever thought that a massive-enough database should be able to give you some reading suggestions? Well, LibraryThing does all that. I started using it yesterday, and bought a lifetime account today (it’s free for 200 books, $10/year or $25/life for an unlimited account). Only have 169 books in there, but that’s only two bookshelves and the books lying around my bedroom.
