We add these to the one or more 020s already in the record, and use the
original record for the item since there is no change in text.  We
record "(PermaBound)" or whatever after the new ISBN.  We make no other
change to the bibliographic record.  The holdings record might say "c.3
PermaBound".

We see the utility of the number for replacement ordering.  We
see it as no greater problem than having the hardback and paperback,
or library and trade bindings,  020s in the record.

As for prime source, we don't see it as a problem.

Since I doubt if these rebound items are sent to LC as copyright
material, I doubt if we will see an LCRI.  Perhaps a proposal to the
JSC?

In terms of record matching by ISBN, multiple ISBNs are a reality.
There are ISBNs for the set, and for each volume, for example.  Matching
software is going to have to be sophisticated enough to deal with it.  I
know of no library which does separate records for the hard and
paperback versions of a book printed from the same plates and issued at
the same time by the same publisher.  The later addition of a binding is
no different in our view.
