Introduction

This release of changes to WorldCat Validation is the first of a series related exclusively to the OCLC-MARC Authority Validation Rule Sets for the Library of Congress Name Authority Cooperative (NACO) and Subject Authority Cooperative (SACO) Authority Files.

Included are selected Authority elements previously documented mostly in the following MARC 21 Format for Authority Data Updates issued by the Library of Congress:

The corresponding “Authority Record Changes” sections of the following OCLC Technical Bulletins have also documented most of these selected Authority elements for WorldCat:

The new Geographic Area Codes and Language Code listed below were announced in the respective LC Technical Notices that are referenced.

All MARC Authority elements listed below may now be implemented in NACO Authority records. The next quarterly updates of the LC Descriptive Cataloging Manual Z1: Name and Series Authority Records, DCM Z1 for short, and the LC Guidelines Supplement to the MARC 21 Format for Authority Data, 2002 Edition with Subsequent Updates, also known as "The Blue Pages," are scheduled for April 6, 2020, and will incorporate the listed Authority elements. For MARC Authority elements not listed below, continue to follow the instructions in these documents. LC will also soon announce the availability of revised NACO Training documents, which are in progress.

Both LC and OCLC will distribute follow-up announcements in coming weeks about the implementation of additional MARC Authority elements. In the meantime, please continue to follow the current instructions in DCM Z1 and the LC Guidelines Supplement for elements that are not listed below.
