Here is a really cool site where you can catalog your books. I am trying to use it to keep track of what books I have read. It has really improved over the last year since I have been a member, but I am not very good about adding books, hence I am not a paying member yet. I definitely own more books than are listed under my library. I keep thinking I will remember to add books as I check them out and/or buy them but I usually forget. One of the cool features is you can see book suggestions based on what is in your library or unsuggestions... Maybe a goal for 2008 should be to update frequently?
It is also the source of the cool widget located on the top right of my blog.
Anyway check out my library....
