Post-Resource Description and Access (RDA) Test Policies at NLM®
NLM will not create original Resource Description and Access (RDA) bibliographic records during the interim period after the US RDA Test ended on December 31, 2010 through the announcement of any implementation decision, which is expected in June 2011. Some US RDA Test participants who are Program for Cooperative Cataloging (PCC) Name Authority Cooperative (NACO) participants will continue to create RDA bibliographic records after December 31, 2010. Other non-US RDA Test participants are creating RDA records now and may/will continue to create RDA records.
NLM will use RDA records that come over as copy cataloging including the updating of any RDA Cataloging in Publication (CIP) records created during the test period. In both categories, the authorized access points on the bibliographic records will be made in RDA forms. If the RDA form of an access point does not match an already established authority record, NLM will not code these records with "pcc" in the 042 field—since they do not follow the post-test practices established by the PCC.
For Anglo-American Cataloguing Rules, Second Edition (AACR2) original and copy cataloging NLM will follow its normal cataloging procedures, with the following exception: If the authorized access point on an AACR2 record is coded RDA, the RDA form of the heading will be used in the bibliographic record. Records will be coded with "pcc" in the 042 following normal NLM practice.
