OCLC policy statement on RDA Cataloging in WorldCat for the U.S. testing period and beyond
- 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.
- 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.
- 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.
RDA Blog : RDA Blog 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 Cataloging Rules (AACR2). This blog lists description and links to resources on Resource Description & Access (RDA). It is an attempt to bring together at one place all the useful and important information, rules, references, news, and links on Resource Description and Access, FRBR, FRAD, FRSAD, MARC standards, AACR2, BIBFRAME, and other items related to current developments and trends in library cataloging practice.
RDA Blog History: RDA Blog was created by Salman Haider, a Cataloging & Metadata Librarian Blogger & Online Social Media Expert from India. RDA Blog embarked on its journey to provide useful information to Resource Description and Access (RDA) in August 2011. It received good response from librarians, catalogers, and library professionals from all around the world. It is interesting to note that the first hundred thousand pageviews to RDA Blog came in 3 years, but it took just 8 months to reach another hundred thousand pageviews. At present it is viewed at a rate of fifteen to twenty thousand times per month. RDA Blog is widely followed in social media.
