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:

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.
