From AACR2 (Anglo-American Cataloguing Rules, second edition) to zoom, this reference comprising some 4,500 terms used in library and information science updates the 1996 edition with about 2,000 new terms. As a stated aim is to make the dictionary a 'one-stop shop,' no full definition cross-references are supplied for synonymous terms. Terms defined elsewhere appear in bold, and vocabulary from fields such as computing and management are noted. Perhaps the next edition will be a Web one as the compiler, with 50 years of professional experience, forecasts.
