Towards robust intermediaries
Jon Udell: The basic LibraryLookup bookmarklet is a kind of intermediary. It coordinates two classes of services -- Amazon/BN/isbn.nu/AllConsuming and your local library's OPAC -- to facilitate a lookup. I couldn't resist trying to create another intermediary that would facilitate a purchase request.
Excellent.
Question to ponder: what is the chance that this code will continue to work, unmodified, three years from now? What technical, sociological, and legal innovations will be required to make this come about?
