xISBN and the lovely people at OCLC
"is a library web service that supplies International Standard Book Numbers (ISBNs) associated with individual intellectual works represented in the OCLC WorldCat database. Give it an ISBN, and it returns a list of associated ISBNs."
What's really cool about this (free) project is that you can submit your library's homepage URL and the people at OCLC will create a bookmarklet for you that you can simply drag onto your browser bar. This bookmarklet will not only extract the ISBN from any web page you look at, it also searches the WorldCat database for associated ISBNs (for different editions etc). I submitted the URL info for UC Library and I am hoping to get on their list-even though the ILS system we use is not open source compliant.
You can see an overview of xISBN here
And you can submit your library URL into the system here
Update 5/26/2006...
Utica College Library is now on the OPAC list. I have installed the bookmarklet and the only problem I have is that when you first try to use it you are prompted for your card number and PIN. It is really neat though. Have you tried it?
