Getting Alternate ISBNs
I’ve added the following function to the version of the XMLOPAC class I use internally so that I can get alternate ISBNs using OCLC’s xISBN service. The result, of course, is an array of ISBNs that serves all sorts of meaningful purposes, like finding an ASIN when you don’t find a match for the cataloged ISBN.
