Create or modify field 040 as follows:
- For any original cataloging (defined here as any record created
without copy for the item/edition in hand; edition copy qualifies
as original, but not compare copy) add "PSt" in 040 |a.
- For any record created (typed into the AddTitle template) and
for all original cataloging, add "PSt" in 040 |c.
- When importing matching copy, leave 040|a and |c as they exist
in the record; they tell who did the cataloging and who input
the record. When making changes to copy, add "|dPSt" at the end
of the 040 field. The subfield "d" is repeatable.
