RDA Blog or Resource Description & Access (RDA) is a blog on Resource Description and Access (RDA), a new library cataloging standard that provides instructions and guidelines on formulating data for resource description and discovery, organized based on the Functional Requirements for Bibliographic Records (FRBR), intended for use by libraries and other cultural organizations replacing Anglo-American Cataloguing Rules (AACR2). Free for everyone Forever.
To help LC in carrying out its responsibilities for (1) the ongoing development of RDA, and (2) the creation and/or revision of training materials supporting documentation for LC, PCC, and the U.S. library community, most of the LC cataloging staff who participated in the U.S. RDA Test will return to using RDA for cataloging starting in November 2011. Documents identifying changes in LC policies from those followed during the U.S. RDA Test and refresher training materials prepared for LC’s RDA cataloging staff will be posted on LC’s web site for preparation for RDA (http://www.loc.gov/aba/rda/).

At its August 24 meeting, the Committee of Principals requested that ALA Publishing on behalf of the Co-Publishers of RDA: Resource Description and Access work with the JSC and the U.S Test Committee to formulate a plan for the rewording of RDA and to define the role of the copy editor.
The search to identify a copy editor with the knowledge and skills to take on this assignment is underway. More details about the copy editor and the rewording plan will be shared as soon as they become available.
The Policy and Standards Division, part of the Acquisitions and Bibliographic Access Directorate at the Library of Congress, is launching a new website as the Library prepares for RDA. The site is located at: http://www.loc.gov/aba/rda/. There are links to training documents, presentations, exercises, and examples of records as well as to other RDA related sites. Many more links will be added as items are created, edited, and updated as preparations for RDA proceed. The page originally created for LC documentation related to the US RDA Test will no longer be maintained. Links from that site will be migrated to the new site over time as appropriate.
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 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.
MARC 21 Updates 9, 10, and 11 include all changes to MARC for use with RDAapproved through 2010. The list below has been updated to include changes under consideration in June 2011. Those not-yet-approved changes are indicated below as "proposed" or "under discussion", and are linked to their relevant MARBI Proposals and Discussion Papers.
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 the testing participants produced records, and a 3rd 90-day period in which the Steering Committee for the testing evaluated the results and produced its report. That report has now been shared with the wider library community. Widespread adoption of RDA within the U.S. is not expected now until January 2013 or later. OCLC is committed to supporting OCLC members who wish to implement RDA in their libraries but will not require that all libraries adopt RDA.
Many of the institutions that participated in the testing are OCLC member libraries and have added RDA-based records to WorldCat, either online through Connexion or through batchloading. OCLC cataloging members who are not testing participants also have tried RDA Cataloging. Some RDA test participants, including the Library of Congress plan to continue cataloging using RDA with some or all of their cataloging production until the implementation date. OCLC urges that cataloging staff members take time to become familiar with the content and use of RDA before beginning the creation of RDA records. Library of Congress staff have made available a variety of training materials that will help in the familiarization process.
Until further notice, OCLC asks that the following protocols be respected by OCLC member libraries:
Catalogers may contribute original cataloging using RDA to WorldCat if desired. (040 $e with value rda and Leader/18 (Desc) coded i if ISBD punctuation is used or blank if not).
For materials other than continuing resources, catalogers are asked NOT to edit a WorldCat full-level master record (ELvl values blank, 1, 4, 8, I, and L) to change it from one set of rules to another. In other words, if the record was created according to AACR2 (and coded as such), please do not change the master record to RDA. If the record was created according to RDA (and coded as such), please do not change the master record to AACR2.
For records describing continuing resources, a cataloger may change a record from AACR2 (or earlier rules) to RDA as part of the process of updating information in the record. Once the record has been changed to RDA, please do not change it back to AACR2.
If a record is a minimal-level or less than minimal-level record (ELvl values K, M, 2, 3, 5, and 7), a cataloger may change the record from AACR2 to RDA as a part of the process of upgrading the record to full-level (ELvl values blank, 1, 4, and I,). As in the previous bullet, please do not change it back to AACR2 once it has been upgraded and changed to RDA.
If an existing record is not coded as following either AACR2 or RDA (i.e. coded blank or i in Leader/18 (Desc) and 040 $e is not present), a cataloger may edit the master record to follow either AACR2 or RDA when upgrading the record.
When performing copy cataloging, catalogers may LOCALLY edit records created under any rules to another set of rules. Please do NOT replace the master record for this purpose (unless upgrading as outlined in the previous 2 bullets).
If a record created according to either AACR2 or RDA already exists in WorldCat, please do NOT create a duplicate record according to the other code. Such duplicates are not within the scope of the OCLC policy on parallel records and OCLC staff will merge them if found.
These protocols, which applied for the duration of the nine month RDA test period, continue to apply until further notice. OCLC will reconsider this policy during the remainder of 2011 and will seek comment from the OCLC membership on how widespread implementation could affect WorldCat before making policy decisions going forward.
