I really like Library Thing. My catalog is at:
I especially like the rating feature, suggestions and unsuggestions--hilarious! It is so easy to use. I'll have to keep adding more titles to see how my reading interests fit with others in the fantasy area.
This assignment is set up perfectly for our career. I plan to return to become more and more familiar with this site and to add more to my catalog. I've considered adding all the fantasy books I own, but I would have to upgrade to a paid account as I own over 600 paperback fantasies.
