    Abstract
    In 1986 Libraries Unlimited published Cochrane's book, Improving LCSH for Use in Online Catalogs; Exercises for Self-Help with a Selection of Background Readings. This was preceded in 1981 by an ERIC publication (ED 208 900) by Cochrane, with Monika Kirtland Bibliographic and Bibliometric Essay which documented critical views of LCSH and an analysis of vocabulary control in LCSH (parts of which were published in Cataloging & Classification Quarterly' 1(2/3) (1982), 71-94). Three features of LCSH will be re-examined to check on progress since the time of these earlier publications: notes, structure of relationships between headings in the list, and links between Library of Congress classification numbers and LCSH or other vocabularies
