Abstract

Describes the origins and development to date of OLUC, the worldwide bibliographic database of OCLC launched by Ohio College in 1971. OLUC now has over 34m records, with publications in 400 languages. Aftere arly criticism of database accuracy, OCLC began quality improvement programmes in the 1990s, introducing the TechPro 'turnkey cataloguing' and Prompt-Cat acquisitions services. Explains how OLUC solved the 3 problems of duplicated records, sparse bibliographic data, and too many author and subject headings. OCLC has invested heavily in improving data quality, launching an authority control service in early 1996. Provides details of several cooperation programmes started by OCLC, e.g. Conser, USNP, NACO, Enhance and others
