Abstract
Research leading to a detailed content analysis and profile of the Library of Congress Classification schedules. A description of the design, methodology, and preliminary findings of research in progress. Final results of the study are expected to aid the Library of Congress in the development of a MARC format for its classification schedules and in the conversion of the schedules into machine-readable form. LC's ultimate goal is the design of an integrated system which will permit on-line editing, maintenance, and control of the schedules, on-line classification and shelflisting procedures, the production of the schedules in two or more physical formats, and the use of LCC to enhance search capabilities in on-line catalogues.
