I’ve decided to spend some time on organizing my books a bit. After doing some searching I ended up with 2 interesting sites: Librarything & Gurulib. Both looks quite promising. Librarything is semi-commercial (the first 200 books are free, if your collection is larger you have to pay a low fee). Gurulib was started as an attempt to help track borrowed books, movies, music, games and software between friends.
My first impulse was going for Librarything, since it appears to be the biggest. But then I tried to import my Amazon order history, by following the instructions on their FAQ page. And now I keep getting fatal errors when trying to add books. I hope that I only borked my own library, and not their entire database… 
Anyway… Check out my (incomplete!) libraries here:
