Access to AACR2 via Cataloger’s Desktopafter March 31, 2013

In January 2012 the Library of Congress announced that it would transition from AACR2 (Anglo-American.Cataloguing Rules, second edition) to RDA (Resource Description and Access) on March 31, 2013.  AACR2 is currently available via LC’s web-based cataloging documentation subscription service, Cataloger’s Desktop, as well as through RDA Toolkit. In keeping with LC’s decision to switch from AACR2 to RDA, Cataloger’s Desktop will simultaneously change how access to AACR2 is provided.On April 1, 2013, if you subscribe to both Cataloger’s Desktop and RDA Toolkit (which includes an online version of AACR2), you will continue to have access to AACR2. If you subscribe to Cataloger’s Desktop but not to RDA Toolkit and want online access to AACR2, you will need to establish an RDA Toolkit subscription at RDA Toolkit
