Abstract: A description is presented of the project at the University of California Library Automation Program to cumulate the 1966 through 1971 supplements to the Library of Congress Subject Headings. The University of California Institute of Library Research MARC processing software, BIBCON, was used, with specially written programs. The resulting cumulation was edited, printed in book form, and made available to libraries. The final task involved merging six MARC files into one file of over 125,000 records and then printing that file in a format similar to that of LC Subject Headings. The project was a cooperative effort with participation by people from several UC campuses.
