    Abstract
    Reports a survey of all academic members of the Association of Research Libraries in the 4th quarter of 1997 which examined how academic libraries incorporate electronic information sources into their reference activities and the effects on libraries services. There was a response rate of 68 per cent, Compares results surveys carried out in 1991 and 1994. The survey covered: numbers of computers access options (intermediary, end user online, CD-ROM locally loaded databases or those accessible through the library catalogue and the Internet. There is a trend away from print resources, particularly indexing and abstracting materials, and away from CD-ROM LANs and local loading of databases towards remote online resources

    Abstract
    Describes the variety of search services supporting library reference functions offered by the RLG in the USA. The best known of these is RLIN, the massive bibliographic database and related services originally developed for shared cataloguing. In the last few years RLG has added CitaDel, an online search system that provides access to indexing/abstracting databases; and Zephyr, a Z39.50 server that amkes the RLIN and CitaDel databases searchable through a library's online catalogue. RLG also offers document delivery connections, including Ariel and Internet based document delivery software, for a full complement of online reference support for academic and public libraries

    Abstract
    Reports on a survey of ARL (Ass. of Research Libraries) members in the USA in 1994, which sought to find out the electronic reference services that are offered by these libraries and how the services affect reference staff, the expectations of users, and user instruction. The services covered include CD-ROM, intermediary online searching, end user online (e.g. FirstSearch), tape loaded databases and user access to the Internet, including electronic mail facilities. Highlights the additional workload the provision of these services involves, and the sometimes unrealistic expectations of users especially with regard to Internet resources

    Abstract
    Report of a survey 96 (out of 119) US and Canadian member libraries of the Association of Research Libraries (ARL) to determine their use of on-line and CD-ROM data bases, including OPACs. 4 catalogues were identified: on-line mediated searching (97%); CD-ROMs (96%); end-user on-line searching (45%); and locally mounted magnetic tapes (37,5%). The latter option is expected to be the most widely used option in the new future. Although CD-ROM caused some migration from on-line, most migration was from printed sources to CD-ROM. Tables show: on-line hosts most used for intermediary on-line searching; on-line data bases most after searched by intermediaries; end user on-line systems offered by most libraries; the 20 most popular CD-ROM data bases; and the 8 magnetic tape data bases accessible on OPACs

    Abstract
    Gives a brief account of the various kinds of reference sources available to libraries, from remote online sources to locally mountes databases to printed reference works. Also provides a short historical account of electronic reference sources. Sees a role for each medium in the library and gives broad guidelines for choosing to provide a variety of these media

    Abstract
    Discusses the advent of software packages (termed front end packages) which are installed on PCs or Macintosh machines and provide the user with an interface to online databases. The packages involved usually provide graphical user interfaces (GUIs) and are dedicated to particular online systems. Focuses on KR ProBase which was introduced by Knight-Ridder in 1995 for information specialists to search DIALOG and DataStar (though not yet with a single interface). Describes the features of this product. Concludes with a brief discussion of the alternatives to host specific software packagaes, Z39.50 and Web browsers such as Netscape

    Abstract
    Discusses a number of trends in the provision of commerical research online systems to end users, as opposed to professional intermediaries. The trends highlighted include: Web versions of, for example, FirstSearch and EBSCOhost; end user access via the library, which cushions the user from direct paymant for use; the integration of information sources in specific subject areas; the rethinking of proprietary software solutions; and the provision of specialized products with a very specific customer focus

    Abstract
    Discusses the familiar problem of users are now confronted with the needs to impose order on myriad sources of information and to present them in an integrated way to users. Describes an attempt to provide such integration in the engineering field, Engineering Information Village, or Ei Village, produced by Engineering Information Inc. It resembles a WWW site, and integrates a traditional online abstracting and indexing service with access to WWW sites in the engineering field, contacts to engineering consultants, and access to other sources of interest to engineers. Explains how the metaphor of the village is carried though in the service and stresses the vetting process which seeks to guarantee that sources provided are authoritative. Also details the pricing of the service

    Abstract
    Database usage data from a random sample of academic and public libraries in the U.S. and Canada reveals patterns of use in selected types of libraries. Library users in both public and academic libraries tend to use commercial online databases most frequently early in the week, mid-day, and at times that correspond to the academic calendar (November in this six-month sample.) The mean number of simultaneous users is correlated with the size of the population served and the number of workstations available, but relatively low numbers of users are simultaneously logged on to research databases at all sizes of libraries. A questionnaire sent to these same libraries identified many other factors that might influence database use, including levels of instruction, availability of remote login, placement of a database on the library's homepage, although none of these factors was found to be statistically significant

    Abstract
    The study investigated the factors of response time, coverage, content and cost in CD-ROM and online versions of 2 popular databases: SilverPlatter Information Ins.'s and DIALOG's version of Psychological Abstracts (PsycINFO and PsycLIT) and Sociological Abstracts (Sociofile and Sociological Abstracts). Results confirm that, though the databases may be similar, significant differences do exist. Specifically, online searching gives a more consistent or predictable response time and yields greater currency, consistency and coverage

    Examines why online systems and CD-ROMs are producing a greater need for bibliographic instruction. Most online systems and CD-ROMs operate with the same software developed for the first online systems 20 years ago. Innovative search techniques such as natural language have spread from inhouse databases to the commercial online and CD-ROM environment. Personal Librarian and Westlaw Is Natural represent the online second generation. Discusses Personal Librarian; CD-ROM products; online expansion and DIALOG and Personal Library Software
