The Coop Team has been receiving reports from PCC libraries that some
members are revising existing series authority records to include the $5
DPCC code in the treatment field. This is particularly confusing when it
has been used to replace treatment decisions by LC not to trace.
I've been asked to remind members that, per Z1 (Yellow Pages) section
64X, Series Treatment, the code $5 DPCC is used in creating *new* series
authority records, not in revising exisitng records.
Also, the code $5 DPCC is not to be used in fields 644 (analysis) or
