How will RDA affect the way that records are coded in MARC 21?
The RDA/MARC Working Group has developed a number of proposals for changes to the MARC 21 formats to accommodate the encoding of RDA data. See the listing of proposals and discussion papers at http://www.rda-jsc.org/rdamarcwg.html. The JSC expects that most RDA data elements can be incorporated into the existing MARC 21 structure using current MARC 21 guidelines for coding and order of data elements. Thus, in most cases, RDA will not necessitate users of MARC 21 to make changes to the way their MARC data displays. Draft Appendix D of RDA contains a mapping from MARC 21 Bibliographic to RDA, and Appendix E contains a mapping from MARC 21 Authorities to RDA.
