This is an interesting situation that is worth some discussion. On
November 12, we upgraded a record in OCLC to PCC status, and as part of
that we made a SACO subject proposal and a SACO classification proposal.
The record in question is OCLC 268662166. The title of the work is:
Capture-based aquaculture : global overview
We made a subject proposal to establish "Capture-based aquaculture" and at
the same time we proposed a new class number for this subject (SH137.33).
The proposals were approved on weekly list 50 and the subject authority
record was added to OCLC on Dec. 11.
Subsequent to our authenticating this record as a BIBCO record, another
PCC library changed the subject heading to "Cage aquaculture". I'm not
sure which library did this, because there are four PCC library codes
after ours in the 040 of the record. I assume that whoever made this
change did so because they didn't find the heading Capture-based
aquaculture in the OCLC authority file. It was still working its way
through the proposal/editorial process at LC. If the cataloger who
changed the heading to a much less specific or appropriate heading had
checked the LC Authorities web site (http://authorities.loc.gov/) they
would have seen that the subject heading on the record had been proposed
through SACO. They should not have altered it on the BIBCO record.
So... it would be good to remind all catalogers that if a record is
authenticated as a PCC record and they don't find a subject heading or
classification number that is on that record in the OCLC authority file or
on Classification Web, it's almost certainly because the heading or number
has been submitted through SACO. They can check on proposed subjects by
looking in Library of Congress Authorities.
I've changed the subject heading on OCLC #268662166 back to what it was
and should be: Capture-based aquaculture.
It also strikes me as odd that someone modified the 530 note that we had
on the record from "Also issued electronically via World Wide Web in PDF
format" (which is text that comes right out of AACR2) to the much less
specific "Also issued online". It's not clear to me why a cataloger would
change that note on a BIBCO record.
Happy Holidays everyone,
