If this helps anyone, the British Library distinguishes between LAC's
authority file and its catalogue in citations in our NACO records, using
the same formula as for records from LC's files, or our own, ie:

670 |a LAC auth. file [date]
670 |a LAC database [date]

That is, we cite the source as LAC's authority file or database, in 670

Subject: [PCCLIST] citing LAC headings, bib or auth

Dear CPSO:

We NACO participants now have access to both LAC bibliographic and
authority records. When citing what we find in 670, should we try to
differentiate between headings found on bib records and those from
authority records? It seems to me to be worth it to include some of the
information from an authority record, e.g., full birth date, full name,

A few examples in DCM Z1 Appendix 2 might be helpful (exemplary, not
prescriptive, of course).

Possible example:
LAC via Amicus, June 23, 2007 $b (hdg.: Gait, Darlene, 1969-; usage:
Darlene Gait) authority record (Gait, Darlene, 1969-; Darlene
Emmerrecianna Gait, b. Oct. 10, 1968)

Thanks for advice.
