Today I found a link to a website called LibraryThing. It is basically a place to store books that you have and to organize them based off tags. It comes with quite a few importers so you can import from a csv, text file, your Amazon wishlist, and more. Even though their servers are getting hit very hard right the website is still pretty response (although the automatic importer has a 13 hour queue on it). If you enjoy reading books, it is worth a checkout
Here is my list that I have been able to build today by hand.
