RDA and Authority Work

RDA and LC Authority Records

As of April 1st 2013, every record that Library of Congress creates is an RDA record in its descriptive aspects and in its headings. In preparation for RDA implementation, work to update the LC Authority file was completed in 2 phases:

In Phase 1, records whose 1XX fields are incompatible with RDA were identified. A 667 field was added stating that the 1XX field cannot be used under RDA until the record has been reviewed and/or updated.

In Phase 2, the authority records with 1XX fields that could be modified automatically were updated.  The changes include spelling out of abbreviations such as Dept., Latin terms (ca.) and modification of Bible and Koran headings. This phase was completed in March 2013.

LC authorities in our local UTL Authority file were updated in 2014 and bibliographic records linked to these authorities were adjusted.
