Machine-readable data bases of bibliographic records provide the substance for online catalogs. In order for a data base to be a catalog, however, it must have a logical organization which collocates related items. Authority control imposes this organization. The Ohio State University Libraries began use of LCS (Library Control System) as its official catalog in summer I982. LCS achieves authority control through a headings file, which: 1) serves as an authority file by displaying the verified form of headings used in the catalog and by linking related headings; and 2) organizes and provides access to the data base by serving as an index to the bibliographic records. This system continues the organizational philosophy of the card catalog, enhancing it with the advantages of automation. The machine link between headings files and bibliographic records facilitates change and modification of the headings. This new application of authority control- in LCS illustrates the theory of authority control in online catalogs.
