Hi William, According to the book KEV format (defined here: ttp://tinyurl.com/2psmkq) the max occurrence of the isbn key is 1. I'm assuming that by extension that means that the rft.<m-key> (i.e., rft.isbn) form is also limited to one occurrence. So specifying multiple ISBNs that way is a no go.
You can however specify multiple referent identifiers. From the KEV Context Object format matrix (http://tinyurl.com/2r5hsc): "Multiple instances of rft_id do not indicate multiple Referents, but rather multiple ways to identify a single Referent" So I *think* what you could do is this: "rft_id=urn:isbn:<isbn1>&rft_id=urn:isbn:<isbn2>&..." Also, I'd be remiss not to point you to a more authoritative list for OpenURL questions: http://listserv.oclc.org/scripts/wa.exe?A0=OPENURL. Although I'm sure there's plenty of overlap in interest/knowledge in the subject between the lists. -- Jay Luker [EMAIL PROTECTED] Software Engineer, Ex Libris Inc.
