    Abstract
    In 1973 a seminal research study was conducted which concluded that subject analysis for African American studies resources was seriously inadequate and that the area was neglected in research. 20 years later, revisits the relevant issues, specifically examining Library of Congress Subject Headings against the capabilities of online catalogues to retrieve materials relating to this body of literature. Concludes that improvements have been made but that problems continue to exist. Offers prescriptive measures for resolving the remaining problems

    Abstract
    The nature of authority control is defined, issues concerning it described, and their implications in connection with the use of large-scale bibliographic databases are analyzed. Some of these issues include the nature of standards, quality control and the differences involved in using centralized as opposed to decentralized databases. Economic considerations are deemed important, especially in view of planned linking of large-scale databases.
