"my books" web site?

Does anyone know of a web site with a full ISBN catalog of books where you can build a "my books" collection? I'm thinking of something similar to the "My Movies" section of <http://www.imdb.com> or the "DVDs I Own" section of <http://www.tvshowsondvd.com>. Amazon gives you a checkbox that says "I own it", but no way to list all the books you've marked as such. I think they only use this for product suggestions and don't let you build a collection list on their site. There seem to be software products devoted to book collectors, but I'm looking for something really simple.
