Only participants in the PCC URIs in MARC Pilot Project are currently allowed to add or edit 024 fields.  For everyone else, the moratorium remains.  

The DCM Z1 should be followed by NACO libraries.  It will be revised when field 024 can be added by any NACO participant:

“Do not add field 024 to an authority record. As of September 2018, there is a moratorium on adding this field in authority records (see An announcement will be made when catalogers may use this field again.”

Hi all

Sorry I deleted the response to this and I've just had a query from our library's management regarding ISNI and its use in records. What is the official position on this?

Hello all

deepest apologies for being behind the curve on this - but are we now allowed to put ISNI or VIAF into the 024 of name authority records?

There was a moratorium on adding these and I heard that a decision on adding the 024 fields was to be made at the 2019 ALA Midwinter.   However, I haven't heard anything.

I did a quick search for the PCC Task Group on Identity Management in NACO group - but didn't find anything that addresses this.

Thanks for any feedback
