Yep. See RFC 2141 for the URN syntax spec. RFC 2168 for how to 
find the server that is authoritative for that URN namespace. And
then see RFC 2169 for a trivial (and in need of updating) way
to query for the various locations of the resource.

The problem is that while the proces is defined and set in general.
The organization that is authoritative for ISBNs hasn't registered
for the namespace or setup the resolvers yet.

Both... ;-) And a little bit of advertising for the URN scheme to boot! ;-)
