An April 2 post to the RDA-L user list by Alan Danskin announced the British Library's implementation of RDA effective April 1, 2013. The full text of the post follows.
From the 1st April 2013, RDA: Resource Description and Access, replaced the Anglo-American Cataloguing Rules, 2nd edition, as the British Library’s official descriptive cataloguing standard, for records added to the British National Bibliography and British Library MARC Exchange files.
British Library exchange files will continue to contain a mix of RDA and AACR2 records over the foreseeable future. The Library will continue to re-use AACR2 records when no equivalent RDA record is available. DCRM will continue to be used, where appropriate, for the description of rare materials, but authorised access points and other elements that are out of scope of DCRM will be constructed following RDA, not AACR2.
The Library has a commitment to the enhancement of its legacy data; including records converted from printed catalogues. Amendments to these records will generally be made in conformance with RDA. Records will not be re-coded as RDA unless fully upgraded
The Library's contribution to LC/NACO Name Authority File switched to RDA during 2012.
