The DCM Z1 instructions address the creation and update of name and series authority records (NARs and SARs).  Use them in connection with RDA: Resource Description and Access, Library of Congress-Program for Cooperative Cataloging Policy Statements (LC-PCC PS), and other sections of the Descriptive Cataloging Manual (DCM).  These instructions supplement the MARC 21 Format for Authority Data and generally do not repeat information found in the format.
