Anglo-American codes are examined to determine the implicit or acting concept of work in each, in order to trace the development of our current implicit concept of work, as embodied in AACR2R. The following conditions are examined, using comparison tables: 1) same work with different appendages (illustrated works, music with text, texts with commentary and/or biographical/critical material, scholia); 2) separately published parts of a work produced by the exercise of several different functions; 3) appendages to a work published separately (commentaries without text, concordances, continuations, indexes, sequels, supplements); 4) change in title of a work. A trend away from the collocation of the editions of a work called for by the second objective of the catalog is identified. It is suggested that this tendency stems from failure to take advantage of newer technologies for building catalogs.
