    Abstract
    One of the most common errors in cataloguing library materials involves miscoding of the nonfiling indicator of title fields. Notes the extent of the problem and its negative effect on searching in the library's online catalogue and surveys how librarians have approached solutions to the problems. Describes how the major library automation system address this problem

    Abstract
    3 months of transaction records from the INNOPAC online catalogue, at Adelphi University, New York, were examined. Patron searchers rely on the standard access points of subject, title, and author for nearly 90% of their searches. Library employees search by title nearly 50% of the time. Title searching predominated among technical services staff as well as public service staff. Approximately 30% of staff searches and 40% of patron searches retrieved no records. Patrons were 10 times more likely than staff to make a search resulting in 500 or more hits

    Abstract
    Presents results of 2 user surveys of the Innopac OPAC developed at Adelphi Univ. Library, New York State. 1.: how long users spend at the terminal; how the length of searches vary; how session commands were distributed; how user behaviour varied by session and length of session. 2.: unsuccessful searches: author searches; title searches, and subject searches

    Abstract
    Reviews the potential revolution in the creation and smooth delivery of information on an OPAC released by the MARC 856 field. This offers the catalogue users an active link to a WWW site. Predicts the use of such links for accessing texts or showing locations within the library. Outlines the problems of maintaining the field 856 links and some of the solutions that are being applied by information professionals

    Abstract
    Offers a third alternative to the debate over subject vs. keyword searching in libraries. Provides a background of this facts underlying the debate, including the high failure rates among patron subject searches, driven by the public's overall failure to adequately learn proper controlled vocabulary syntax, and the high percentage of erroneous matches generated by keyword searches, driven by the fact that book titles may have nothing to do with the contents. Describes a hybrid approach that uses a keyword index of the subject field, and that reduces failure rates by 75% among one library's patrons. Reports that, in spite of a few remaining imperfections, this system seems to represent 'the ideal marriage of keyword and formal subject heading searching' for library patrons. Lists the Web site location of the catalogue on which the new system was developed
