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, Adam Schiff ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Adam L.
