Title

Subject heading compatibility between LCSH and catalog files of a large research library : a suggested model for analysis

Source

Information technology and libraries. 7(1988), S.288-298

Year

1988

Abstract

Assigned topical and geographic subject headings from a sample of 3.814 bibliographic records in the University of Michigan Library's catalog were analyzed to determine the degree of match with LCSH, 10th edition and to idetify types of heading conflicts that lend themselves to automatic subject authority control. The findings showed a surprising degree of agreement: 44 percent of headings matched LCSH 10th completely. For headings without subdivisions, the match was 88,4 percent. Since 93,6 percent of the topical subdivisions that did not match LCSH were found on the free-floating lists, some consideration should be given to developing a machine-readable file of free-floating subdivisons for matching purposes.
