Automating the Library of Congress Classification Scheme

Potential uses for classification data in machine readable form and reasons for the development of a standard, the USMARC Format for Classification Daata, which allows for classification data to interact with other USMARC bibliographic and authority data are discussed. The development, structure, content, and use of the standard is reviewed with implementation decisions for the Library of Congress Classification scheme noted. The author examines the implementation of USMARC classification at LC, the conversion of the schedules, and the functionality of the software being used. Problems in the effort are explored, and enhancements desired for the online classification system are considered.
