Title

Subject analysis tools online : the challenge ahead

Source

Information technology and libraries. 9(1990), S.259-262

Year

1990

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
