Can't argue with anything that's been said so far. I'd like to point out
the ostensible similarity between the need addressed in this proposal
(masking certain fields from public access) and that already provided in
the bibliographic format by the 355 field. If the 355 definition of
bibliographic field 355 were expanded to allow for field-level marking (the
355 field linked to the fields it controls with subfield $8), then this
field could simply be repeated in the holdings format.
