Phase 1 of the PCCAHITG Phased Implentation of RDA

News about name authority records.
The PCC Acceptable Headings Implementation Task Group (PCCAHITG) has successfully tested the programming code for Phase 1 in preparation for the LC/PCC Phased Implementation of RDA as described in the document entitled The phased conversion of the LC/NACO Authority File to RDA found at the Task Group's page.

Changes to name authority records (NARs) that are not susceptible to a mechanical change under Phase 2 will have a 667 note aded to them with the statement:

THIS 1XX FIELD CANNOT BE USED UNDER RDA UNTIL THIS RECORD HAS BEEN REVIEWED AND/OR UPDATED

Some other enhancements will be made, when applicable, if the record is being updated to add the note (e.g., 046 fields are added to records for persons when the information is available).

If a record is a candidate for a mechanical change in Phase 2, no note will be added to the record during Phase 1.

The records will be changed in the LC/NACO master file at the Library of Congress and the daily distribution to the other NACO nodes will begin no earlier than July 30, 2012 with an initial distribution of no more than 30,000 records per day. Please note that this increase is in addition to the normal daily exchange with the LC/NACO partners that as a consequence will result in larger weekly distribution loads for subscribers to the MARC Distribution Service Name Authorities database. The daily updates will continue until approximately 420,000 records have been distributed. Lessons learned regarding distibution of changed records during this phase will inform the PCCAHITG as they plan for the handling of Phase 2.
