OCLC Policy Statement for the RDA Test

This has been cross posted in several spots. But just in case here’s OCLC’s policy for RDA cataloging during the RDA national test.

OCLC Policy Statement on RDA Cataloging in WorldCat for the U.S. Testing Period

ALA Publishing has allowed free access to RDA from its publication date through August 31, 2010.  Timeline for testing:

  • First 90-day period:  testing participants will familiarize themselves with the content of RDA and the RDA Toolkit.
  • Second 90-day period:  testing participants will produce records
  • Third 90-day period:  Steering Committee for the testing will evaluate the results and produce its report, which will be shared with the broader library community (expected to be around April 2011).

Widespread adoption of RDA within the U.S. is not expected until after this evaluation report is released.  At that time, OCLC is committed to supporting OCLC members who wish to implement RDA in their libraries but will not require that all libraries adopt RDAOCLC urges that cataloging staff members take time to become familiar with the content and use of RDA before beginning the creation of RDA records.

General guidelines on editing records:

  • Do not change an existing full-level master record, for materials other than continuing resources, from AACR2 to RDA or from RDA to AACR2.
  • Minimal-level or less-than-minimal level records may be changed from AACR2 to RDA when being upgraded to full-level; they should not be changed back to AACR2.
  • If a record created according to either AACR2 or RDA already exists in WorldCat, do not create a duplicate cataloged according to the other code.

      MARC is something different from RDA. RDA or Resource Description and Access is a content standard. It is a set of instructions as to how to describe a resource that helps a user identify that resource from others like it or not. MARC21 is an encoding standard used to mark up this description. MARC is also the most widely used encoding schema in the library world making sharing of records easier. RDA can be encoded in MARC, Dublin Core, or MODS for example. As for examples of how RDA can be used and then marked up using MARC, go to the Library of Congress’ website: http://www.loc.gov/catdir/cpso/RDAtest/rdaexamples.html.
