Final Report of the Standing Committee on Standards (SCS) Task Group on Developing Guidelines for Using ISO 639-3 Language Codes for Library Cataloging

The Program for Cooperative Cataloging (PCC) Task Group on Developing Guidelines for Using ISO 639-3 Language Codes for Library Cataloging was charged with developing a set of guidelines for how to use ISO 639-3 language codes in MARC records. These guidelines were approved by the PCC on November 22, 2022. Most of the test recommendations were carried over. The guidelines continue to recommend only using ISO 639-3 language codes in addition to MARC language codes in shared cataloging in order to support interoperability.
