A spin-off of this second solution is for someone other than the NA to keep
the list. This could be one or more trade groups who serve their members by
keeping them up to date without revealing identities. All members of a
particular group promise to post updates to their URCs, and have free
access to the URC updates housed by the group. If the process is
sufficiently automated, the cost for running such a server might be very
low. Groups like OCLC and the ISBN administration might make such a server
available free to its members and cheap to others.

Even if the list is rather long, it only needs to be checked every week or
two. If the updates are stored by date, getting on the most recent ones is
