contents	Library Catalogs: Their Preservation and Maintenance by Photographic and Automated Techniques. Henderson, James W., Ed. Rosenthal, Joseph A., Ed. Automation Book Catalogs Cataloging Costs Library Catalogs Maintenance Preservation Research Libraries Serials The report deals with one basic question: what does a large research library do when its catalog shows signs of serious deterioration? The catalog under consideration in this report was the Main Public Catalog of The Research Libraries of The New York Public Library. The catalog has nine million cards, some of which date back to 1857. A 1965 report by Seoud Matta, "The Card Catalog in a Large Research Library: Present Conditions and Future Possibilities in The New York Public Library", recommended putting the catalog into book form in order to preserve it. This report is devoted to the technical details of preserving the present catalog and planning for the future. Major conclusions of the study are that: (1) the catalogs of The Research Libraries of The New York Public Library be divided chronologically as soon as possible; (2) the present (or retrospective) Public Catalog be reproduced photographically in book form; (3) the future (or prospective) catalogs be produced in a combination of card and book form from a store of machine-readable data; and (4) a Central Serial Record be created to contain acquisition information, cataloging and holdings data, and bindery records for all serial publications in The Research Libraries.
