This is just an impression, but I have found myself getting used to putting an LCSH term like "Actors" in a 374 field.  I've come to think of it as analogous to a subject heading--i.e., if we catalog a book about a particular movie producer, we don't use "Actor" in a subject heading; we use "Actors."  In principle I do find the use of plurals in a 374 a bit awkward but in practice it has come to feel quite normal.  In my mind, also, the 374 determines but is not duplicated by a heading qualifier, and that feels OK too.

Subject: Re: [PCCLIST] LCSH in name authority records


  Do you see any problem with the "controlled vocabulary" terms used in fields 368 and 374 being different from terms used in name heading qualifiers (e.g. "Non-governmental organizations" vs. "Non-governmental organization" and "Poets" vs. "Poet") and representing groups rather than individuals?

  It isn't clear why the authors of RDA chose to adopt a different approach than LC and NACO, and visa verso (I've remarked on the difference --RDA preference for singular terms "derived from" LCSH vocabulary-- in an earlier post), or at least I do not see the need for different approaches, especially for different uses. In fact, some preferring one approach or the other may not think the difference is entirely obvious at first glance.

  At least DCM:Z1 allows either, creating another level of inconsistency: 
[e.g. 374:) "When terms do not come from a controlled vocabulary, use a singular form."

  The problems I mention (along with logic, when referring to single entities), could be resolved by simply having DCM:Z1 revised to read "Use a singular form" period.

  What possible objections could be raised, except to say "But that's not the *present* [LC/NACO] practice?"

Cheers!

It’s efficient for us, as our local copy of the LCSH file is linked to our bibliographic database, and can quickly be consulted.

Theoretically, it was much clearer and more consistent than LCSH, but we dropped it because its potential users found it more effective to use LCSH, as the prevailing standard.
