The history of cataloging rules is often written as a story of continuous improvement toward a more rational and efficient code. Not all catalogers, however, have been in agreement that reform of the cataloging code has been improvement. The debate of the 1950s and 1960s over cataloging code reform, hosted in part by LRTS, is an example of conflicting values in the cataloging community. Seymour Lubetzky's proposal for a cataloging code based on logical principles eventually became the Anglo-American Cataloguing Rules, but many catalogers of the period felt that other values, such as tradition and the convenience of the user, also deserved consideration in the cataloging code.
