(June 2010) (Learn how and when to remove this template message) </Td> </Tr> <P> The Anglo - American Cataloguing Rules (AACR) are included in a national cataloging code, first published in 1967 . AACR2 stands for the Anglo - American Cataloguing Rules, Second Edition . It is published jointly by the American Library Association, the Canadian Library Association, and the Chartered Institute of Library and Information Professionals in the UK . The editor is Michael Gorman, a British - born librarian living in the Chicago area and honored by both the ALA and CILIP . AACR2 is designed for use in the construction of catalogues and other lists in general libraries of all sizes . The rules cover the description of, and the provision of access points for, all library materials commonly collected at the present time . </P> <P> Despite the claim to be' Anglo - American', the first edition of AACR was published in 1967 in somewhat distinct North American and British texts . The second edition of 1978 unified the two sets of rules (adopting the British spelling' cataloguing') and brought them in line with the International Standard Bibliographic Description . Libraries wishing to migrate from the previous North American text were obliged to implement' desuperimposition', a substantial change in the form of headings for corporate bodies . </P> <P> AACR2 exists in several print versions, as well as an online version . Gorman has edited several revisions of AACR2 including a concise edition . Print versions are available from the publishers . The online version is available only via Cataloger's Desktop from the Library of Congress . Various translations are also available from other sources . </P>
