Give it an ISBN, and it returns a list of associated ISBNs. ## Try it out Enter the following URL into your browser window: `http://labs.oclc.org/xisbn/[ISBN]` substituting an actual ISBN for [ISBN]. For example, try: `http://labs.oclc.org/xisbn/0441172717` (0441172717 is the ISBN for Dune, by Frank Herbert.) OCLC's xISBN service is intended to be used by machines, rather than people. A nice example of xISBN in action is OCLC Research's "Find It@Your Local Library" Bookmarklet. We hope you'll try that as well. The bookmarklet approach is one possibility for using the service, but any application that can generate and send a URL could be used with the xISBN web service. Additional uses for using xISBN include: A user viewing a description of a book at an online bookseller wants to know if the work is available from his/her library A library wants to confirm that no alternative versions of a work are available in their collection before sending an ILL or purchase request Library staff want a single search to check for holdings of all editions/printings of a work before making a selection decision about a gift book |
