    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.

    Abstract
    State of the art review of OPACs which suggests a model for their future development based on a redefinition of the roles previously served by the traditional catalogue. Notes the traditional role of library catalogues and considers the ways in which the catalogue's functions can be extended to provide access to the whole of the library 's resources including access to other libraries' collections
