    Abstract
    Results of previous catalog research indicate that users want improvements in subject searching features, noting display of terms related to their topics as especially desirable. This study reports the findings of an examination of subject searchers' use of such a feature provided through online display of authority information from Library of Congress Subject Headings for terms used in the catalog. It was found that, of the terms entered by users, 78 percent were an exact or close match to catalog terms, and another 14 percent matched "see" references. Although additional information was available for nearly half of the searches performed, it was used in only 28 percent of these cases. It is suggested that improvements in subject searching features are needed to encourage use of available syndetic structures

    Abstract
    The authors have studied the transaction counts from two and one-half years activity at the public use terminals of the Ohio State University Libraries' prototype online card catalog to determine what search options academic library patrons use the most often and whether this pattern varies from that reported in major catalog use studies. The preliminary findings indicate significant differences in search strategy that may result from a unique user group that prefers to search the online catalog, more useful searches in the online system, or special search patterns imposed by the computer hardware itself. Both the different searches used by patrons and why they choose them should be important factors in the design of future online catalogs

    Abstract
    This article reports on a low-cost study of the transaction log of an online public access catalog at an academic library. The three goals of the study were to determine failure rates, to study usage patterns, and to investigate problable causes of patron problems when using the OPAC. The study found that failure rates (defined as those searches that produced zero hits) of approximately 40% are common, and that usage patterns and failure rates do not vary greatly over time or from terminal to terminal, but that the distribution of probable causes of user problems varies significantly from terminal to terminal

    Abstract
    End-user searching of NLM online databases during eleven years has been investigated through transaction logs, questionnaires, and follow-up interviews. From 1976 through 1984, pathologists and pharmacists performed 8.313 searches. Highlights of our studies are compared with a review of other end-user research. Volume of searching is directly related to the convenient placement of the terminal in the work place. Slightly fewer than half of of all potential searchers actually search for themselves. Practices of pharmacists and pathologists do not differ in important ways. Nonmediated searchers feel they need answers more promptly than do those who obtain mediated searches. End-users perform very simple searches, mostly using only the AND operator. Problems with techniques are fewer and more easily solved than those with the vocabulary and content of the system

    Abstract
    Three studies were made of the use of COM catalogues at the University of Toronto and the Mississauga Library System: unobtrusive observations, structured interviews, and a timed-search experiment in reel, fiche and card catalogues. The reel catalogue was found to be the overwhelming favourite, almost as popular in the public library as in the academic library, where 82% of the users reported it to be their preferred form of catalogue. However, for nearly all test questions and searcher types in the timed-search experiment, successful searches required less time in the card catalogue than in either form of the COM catalogues.
