A group of 27 library administrators and library computer systems experts met to share their experiences and insights with regard to online catalogs, to review survey results from The Council on Library Resources (CLR) 1982 Online Catalog Study, to review draft documents on the costs and features of online catalogs, and to discuss and recommend actions on matters required to advance the effective development and use of online catalogs. Included in the conference report are: (1) introductory material; (2) background information on the CLR study, which found that online catalogs provide better access to library materials than card catalogs, particularly for subject searching; (3) a summary of the meeting; (4) a description of working group conclusions on areas related to the cost, ideal features, implementation, and problems of online catalogs; (5) the consensus of the conference; (6) a description of concluding comments; (7) a series of recommendations to library administrators, library systems designers, and the Council; and (8) a list of five references. Appendices contain a list of participants; the meeting agenda; and summaries of reports funded by the CLR Online Catalog Study, including the David Bishop, the Research Libraries Group (RLG), the J. Matthews, the Library of Congress (LC), the OCLC, and the University of California Reports. (ESR)
