Other good online bookselling services where you are dealing directly with
the booksellers:

http://www.alibris.com
http://www.abebooks.com
http://www.half.com
http://www.ebay.com

There are other smaller ones with less selection, including ChooseBooks
already mentioned and http://www.bibliodirect.com

There is also a good "master search engine" that searches all the major and
many of the minor sites: http://www.bookfinder.com
