About RDA

RDA: Resource Description and Access was developed by the RDA Steering Committee (formerly the Joint Steering Committee for Development of RDA) as part of its strategic plan (2005-2009) to replace the Anglo-American Cataloguing Rules, 2nd Edition Revised, which were first published in 1978.

RDA is a package of data elements, guidelines, and instructions for creating library and cultural heritage resource metadata that are well-formed according to international models for user-focussed linked data applications.

Details of how to subscribe to the RDA Toolkit can be found on the publisher's website.

RDA: Resource Description and Access is developed in a collaborative process led by the RDA Steering Committee. RSC gratefully acknowledges the contributions of the many institutions and individuals who have generously given their time and energies to the creation of RDA.
