Countdown to RDA Day One

Resource Description and Access (RDA) Implementation Day One has been set for March 31, 2013 by the Library of Congress (LC) and the Program for Cooperative Cataloging (PCC).

Authority records

The LC/PCC Day One for RDA Authority Records is defined as the point after which all new authority records entering the LC/NACO Authority File must be coded RDA. That date is March 31, 2013.

Bibliographic records

There is no Day One for bibliographic records for the cataloging community at large. However, the Library of Congress will also use the March 31, 2013 date as the point at which all new bibliographic records created by LC will be according to RDA guidelines. PCC BIBCO libraries will also begin using all RDA access points on bibliographic records coded “pcc” (MARC 042 subfield $a). Libraries which are not part of the BIBCO cataloging cooperative may continue to use AACR2 cataloging practices.

Libraries switching to RDA should review their profile options with MARCIVE. If you currently have us remove subfield $e, consider retaining $e to reflect the RDA practice of using relator terms or codes.  Profile requests should be directed to your MARCIVE representative.

Hybrid bibliographic records

Processing of bibliographic headings against the national authority file is independent of RDA and will continue as it has during all transitions to new cataloging practices. Bibliographic headings will be flipped to match the authorized term in the corresponding authority file. As in the past, a bibliographic record constructed by new rules may have a heading that conforms to an earlier practice or a bibliographic record constructed by earlier rules may have a heading that conforms to the current practice. These are called hybrid records and are correct.

Conversion of AACR2 authorities to RDA

LC and PCC are currently discussing the feasibility and process of converting AACR2 authority records to RDA. Until the phases for transition are finalized it is uncertain how the flow of updated authority records to local libraries will be impacted, other than there will be a significant spike in the number of changed records. The steps to be taken to transition to RDA authority records after March 31, 2013 are still being discussed by LC and PCC so MARCIVE cannot give further specifics at this time about how we can help with the data flow. Rest assured, we are monitoring developments and participating in the discussion to join you in voicing your concerns to PCC about the significant strain on resources such a massive conversion could cause if handled without sufficient planning.

MARCIVE service

Some libraries have expressed an interest in global changes to bibliographic records to address a mixture of RDA and AACR2 cataloging. When it is closer to the implementation date, and more field definitions are finalized, MARCIVE will offer a service to handle fields, such as the GMD issue, in a mixture of RDA and AACR2 bibliographic records.
