The Amazon products API keeps changing it's name, and has just been changed to Amazon "Product Advertising API" -- it's the one you use to look up books in Amazon and get metadata for them, though. It looks from an email I got from Amazon that ss of August 15th, you'll need to cryptographically sign requests to this API, to have them responded to. It looks like kind of a pain. I think a bunch of people on this list may be using this API. Beware. Instructions for how to cryptographically sign requests the way they want can be found here: http://docs.amazonwebservices.com/AWSECommerceService/latest/DG/Query_QueryAuth.html http://docs.amazonwebservices.com/AWSECommerceService/latest/DG/rest-signature.html Like I said, it's looking like a pain to me. There are lots of details to get right. If you URI-escape not _exactly_ the same way they do, it's not going to work. Etc. Jonathan
