    Abstract
    EPIC, produced by OCLC, is an online computer service for searching the OCLC database using subject, keyword, keyword phrase, and Boolean searches. It is an important new source of information for reference librarians. Reports on the wide variation in its current use. Although welcomed by users as new method of accessing OCLC its automated training program is seen as cumbersome

    Abstract
    Offers advice on making use of the WWW for reference work, focusing on the use of bookmark files of useful site addresses and how to find reliable content by making use of the Web filters set up by universities and other agencies to select the best sources. Also mentions printed guides to Web sites but these have the problem of rapid obsolescence

    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
