Welcome to our wiki page about RDA!

RDA (Resource Description and Access) is the new cataloging code that was published in June 2010 and is intended to replace AACR2, which has been the cataloging code used since 1978. The three U.S. national libraries (LC, NLM, and NAL) coordinated an official test of RDA and announced in June 2011 that they would implement RDA no sooner than January 2013. Many or most academic libraries will likely implement RDA in 2012 or later. Several academic libraries have already implemented RDA as of 2011 and are actively contributing RDA records in our shared database, so there is a good chance of anyone at CUL encountering an RDA record.

The RDA Training Committee continues to plan training sessions for CUL catalogers that will augment the sessions that took place in the spring, summer, and fall of 2011. We hope this wiki will help catalogers become familiar with RDA, in a way that complements the training sessions. If you know of an RDA resource that you have found to be particularly valuable, and you would like to see it posted on the wiki, please notify Tracey Snyder.

Take some time to explore the RDA Toolkit, as well as some of the documentation that we have compiled about RDA, FRBR, and more. (See the "child pages" below.) Don't hesitate to talk to any of us if you have questions!


Adam Schiff has updated his AACR2 vs. RDA presentations (from the OCLC webinars in summer 2011). These are current as of July 2012.
