Implementation of RDA to Bibliographic and Authority Records from the LIBRUNAM Catalog at the Universidad Nacional Autonoma de Mexico

This article discusses the implementation of the new cataloging code, Resource Description and Access (RDA), to the bibliographic and authority records of the LIBRUNAM catalog. In 2010, the Direccion General de Bibliotecas started analyzing this new cataloging code through the use of the RDA Toolkit and other documentation related to RDA. During this process, the core elements for bibliographic and authority records were identified and retrospective changes were automatically carried out using the Aleph Library Management System. For those records that needed modifications, manual updates weremade, while RDA instructions were applied to new records. The updating of each element is described, including carrier and content types, preferred titles in the original language, and conventional and collective titles for religious works. Elements defined in Chapter 9 and Chapter 11, and relationship designators defined in Appendix K were added to authority records for personal names. These retrospective updates were made to 1,500,000 bibliographic records and 73,000 authority records. The adoption of the RDA code in LIBRUNAM accomplishes support for the main user tasks: Find, identify, select, and obtain.
