Abstract

A system based authority control system was essential to support OCLC's large database and the number and diversity of its users. The authority control system had to be able to (1) identify nonidentical heading entries in bibliographic records of the same name, geographic place, or subject, and (2) maintain a link from the erroneous form of the heading to the valid form (i.e. cross reference). Over 3.6 million headings have been corrected as part of these efforts
