Subject: [PCCLIST] Updating UT/expression language authorities
I've been seeing a lot of RDA records with 130 [title].$l [language 1] & [language 2] authorities attached of late. I can't tell you how sad this makes me.
My sense of the matter of updating these records is to create a new authority for each language if it doesn't yet exist in the AF, and request cancellation of original. Is this correct?
I looked high and low for official documentation, and the closest I came was a PCC list thread from 2013, which confirmed my assumption, but the smart money says, "Ask first, then do the work."
