While not a production service, nor as interesting as a LibX extension, I have written an application exploiting XISBN (as well as thingISBN) called "Send it to me": http://dewey.library.nd.edu/hacks/send/ Given an ISBN number, the system will try to identify your book from the local library catalog. If found it will return meager bibliographic information and allow you to have the book sent to you (but not really). If the ISBN number is not found, then it will use XISBN (and thingISBN) to find similar books and allow you to have them sent to you instead (but not really). The purpose of the application is to prototype a simple document delivery service. It is a fun hack, but it often fails because the intermediary Web Services do not return as expected. Put another way, the program could use some error checking. (Pssst. It uses MyLibrary to keep track of patron information.) -- Eric Lease Morgan University Libraries of Notre Dame
