Resource Description and Access (RDA) is a standard for cataloguing that provides instructions and guidelines on formulating data for resource description and discovery. Intended for use by libraries and other cultural organizations such as museums and archives, RDA is the successor to the Anglo-American Cataloguing Rules, Second Edition (AACR2), the current cataloging standard set for English language libraries. RDA was initially released in June 2010. In March 2012, the Library of Congress announced it will have fully implemented RDA cataloging by March 31, 2013. Several other national libraries including the British Library, Library and Archives Canada, National Library of Australia, and Deutsche Nationalbibliothek also planned to implement RDA in 2013.


RDA emerged from the International Conference on the Principles & Future Development of AACR held in Toronto in 1997. It was quickly realised that substantial revision of AACR2 was required, which encouraged the adoption of a new title for what had been envisaged as a third edition of AACR.
The primary distinction between RDA and AACR is structural. RDA is organised based on the Functional Requirements for Bibliographic Records (FRBR). These principles identify both the 'user tasks' which a library catalog should make possible and a hierarchy of relationships in bibliographic data. Descriptions produced using the instructions of RDA are intended to be compatible with any coding schema, including the data environments used for existing records created under the AACR2 rules.

RDA is published jointly by the American Library Association, the Canadian Library Association, and the Chartered Institute of Library and Information Professionals (CILIP) in the UK. RDA instructions and guidelines are available through RDA Toolkit, an online subscription site, and in a print format. Maintenance of RDA is the responsibility of the Joint Steering Committee for the Development of RDA (JSC). The JSC is composed of representatives from the American Library Association, the Australian Committee on Cataloguing, the British Library, the Canadian Committee on Cataloguing, CILIP, Deutsche Nationalbibliothek, and the Library of Congress.

Designed for the digital world and an expanding universe of metadata users, RDA: Resource Description and Access is the new, unified cataloging standard.

Built on the foundations established by AACR2, RDA provides a comprehensive set of guidelines and instructions on resource description and access covering all types of content and media.
