The Concise AACR2, 4th edition is intended to promote a basic set of cataloguing rules and this new edition of the classic text takes into account all the changes and updates made to AACR2 (Anglo-American Cataloguing Rules), Second Edition, 2002 Revision. It incorporates the changes made to AACR2 in key areas such as electronic resources, serials, and cartographic materials; while the Appendices on capitalization, the glossary, and the comparative table of rule numbers have also been fully updated since the last edition. The concise version conveys the essence and basic principles of AACR2 while simplifying the rules to make them more accessible. Those rules taken from the full text have been rewritten and supplied with new examples designed to highlight those more commonly encountered library materials. Although the presentation may be different the end result of using the full or concise versions of AACR2 should be the same. With easy-to-follow examples of rules, the Concise AACR2 is an essential resource for cataloguing students, smaller libraries without full-time cataloguers and occasional cataloguers in libraries of all types and sizes worldwide.
