Hi William,

According to the book KEV format (defined here:
ttp:// 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 ( "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:


Also, I'd be remiss not to point you to a more authoritative list for
OpenURL questions:
Although I'm sure there's plenty of overlap in interest/knowledge in
the subject between the lists.
