    Abstract
    As the online catalog continues to be developed and refined, the question arises as to how the traditional subject analysis tools, the LCSH, the LCC, and the DDC, can be most effectively adapted to the online environment. This article examines the limitations and potentials of these tools and the challenges of incorporating them online. The traditional and potential functions of these tools, the requirements for their becoming efficient online cataloging and retrieval tools, and recent developments toward these goals are discussed

    Abstract
    The chapter deals with methods of subject cataloguing, subject analysis and representation of library materials and outlines the practice of subject searching in library catalogs after the introduction of online catalogs. The vocabulary control methods in the Library of Congress Classification and LCSH are described and strategies for the use of theses systems in online retrieval situations are outlined
