Aren’t the MARC format (http://www.loc.gov/marc/bibliographic/ecbdcntf.html) and by extension, OCLC, confused about the nature of ISNI and ORCID?  These identifiers don’t identify an authority record or a label; they identify a real world object, so why are they used as examples of things that go in $0?

It is even more peculiar that VIAF IDs are given as examples of RWO URIs.  It’s not clear that a VIAF ID identifies much of anything besides a temporary cluster of authority records.

hello Ann,

I recently contacted Jay Weitz at OCLC over this very same issue. Here's what he wrote back:
***

There’s some explanation of what happens with subfield $0 and controlling headings in the BFAS “Control Subfields” chapter under subfield $0 (https://www.oclc.org/bibformats/en/controlsubfields.html<https://urldefense.com/v3/__https:/www.oclc.org/bibformats/en/controlsubfields.html__;!!K543PA!eb8PfWtQqJDX-tmqAVaqmnuHuC1GlUE4lZYw4NlrDz0-cwRrlYA2RzTGjGsXB3wKC0Nrbg$>).



Use of OCLC's control headings functionality in the 1xx, 7xx, and 8xx descriptive access point fields and in the 6xx subject access point fields will remove all instances of subfield ǂ0 in the case of names and subjects controlled to the LC/NACO and LCSH authority files. For access point fields where the control heading functionality is available related to other authority files, the control headings functionality will remove all instances of subfield ǂ0 other than the one linking to the authority record to which the access point is controlled.



Use of OCLC's control headings functionality is preferable to manually entering subfield ǂ0 in cases where the access point can be controlled to a particular authority file. You may enter other applicable identifiers in subfield ǂ0 such as the International Standard Name Identifier (ISNI) or the Open Researcher and Contributor ID (ORCID) in access points which are not controlled to any associated authority file record. However, such identifiers will be removed if the access point is subsequently controlled to a record in an associated authority file.



As official guidelines on the uses of subfields $0 and $1 continue to be developed, there will undoubtedly be some evolution in how all of this interacts in terms of Data Ingest, WorldCat record display, and output options.
***

I think the crucial sentence here is "Use of OCLC's control headings functionality is preferable to manually entering subfield ǂ0 in cases where the access point can be controlled to a particular authority file."

What I took away from this was, at this point, the preferred course of action is to control the heading in OCLC and let the subfield $0 disappear. A subsequent email from Jay seemed to confirm that.

hope this helps,

Subject: [External] [PCCLIST] Incompatible authorities?

Hello -

In record #1089997797, the editor's name in the 700 field is followed by a $0 ("Authority record control number") and a URL, which goes to an LC authority record. His name, however, is perfectly controllable in OCLC in the usual way, but when I control it, the $0 and URL disappear.

Are OCLC authorities and LC authorities incompatible, such that they cannot coexist in the same field? If so, I need to be educated on this matter.

Ann
