MARC21 as Data: A Start

The forty-five-year-old MARC format, currently at version MARC21, is an obvious barrier to the provision of library services in a web-based environment. There is a growing consensus that the time has come for libraries to move to a new format. We cannot, however, decide on a new data format until we at least have an inventory of the data elements that are carried in our current one. Listing those data elements is not simple: over the years this record format has undergone constant change that has pushed the limits of the record structure and introduced inconsistencies in the way that data is coded. This article describes one person’s attempt to decode the content of MARC21. Read full article

ALA 2011: Some RDA news

News from ALA Conference held in 2011
ALA Conference for RDA and RDA toolkit. The U.S. RDA Test Committee met with vendors, testers, and the public, and summarized the results of the test and the reasoning behind their recent decision. The U.S. RDA Test Committee stated that the "rewrite" of RDA will actually be more of a rewording, intended to simplify and clarify some of the instructions. Cataloging practice will not be affected by the rewording. We also learned that the Library of Congress will begin partial RDA Cataloging in November. They will catalog across all subject areas and expect RDA records to represent about 5% of the library's cataloging output. The National Library of Medicine and the National Agricultural Library will not catalog in RDA until full implementation begins.

OCLC Policy on Resource Description and Access (RDA)

OCLC policy statement on RDA Cataloging in WorldCat for the U.S. testing period and beyond

With the installation of capabilities as described in Technical Bulletin 258, OCLC has now implemented most of the MARC 21 format changes for initial support of RDA: Resource Description & Access. OCLC has also implemented links to the RDA toolkit for toolkit subscribers in the Connexion Browser and in Connexion Client 2.3. In the U.S., the Library of Congress, the National Agricultural Library, and the National Library of Medicine coordinated a test that involved those institutions and a group of additional institutions selected from the broader U.S. library community. More information about the testing process can be found on the Library of Congress web site.

The timeline for the testing included a 90-day period in which testing participants familiarized themselves with the content of RDA and the RDA toolkit, a 2nd 90-day period in which …
