    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
    Describes the online end user search service, FirstSearch, provided by OCLC, noting the ways it has developed since its launch in 1991, and the extent of its use in libraries worldwide. Focuses on an important new aspect of the service, the availability of the full text in ASCII format of many of the articles cited in the database, for ordering, viewing and downloading. Also discusses the value of FirstSearch to interloans departments, the costs of the service, enhancements in the searchability of the databases and in the interfaces provided for searching, and the variety of uses to which libraries are putting the service

    Abstract
    Looks to the future of traditional online services, in light of the rising use of the WWW, which brings authors or publishers and readers directly together, without the intermediary role played by online vendors. Gives examples of changes in ownership of online services in the last half of 1997, and notes that the changes all suggest that online vendors must nkow their best markets and stick to them. Concludes that many online vendors will survive but in ne configurations and often with new owners

    Abstract
    Reports on a survey of electronic reference sources and their impact on the work of reference librarians. Reference librarians in university libraries in the Association of Research Libraries (ARL) in the USA were asked to comment on how the library's use of such sources has changed over the past 2 to 3 years and how the work of reference staff has changed. The themes highlighted by the survey include changes in user instructions; the impact of technology; the rising expectations of users; and 'technostress'

    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
    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
    Discusses the rapid increase in the availability of the full text of journals, newspapers, documents and books, online and in CD-ROM, in the recent past, noting that full text now makes up 49% of word oriented databases. Explains the differences between image files, ASCII fullt text which is searchable, and ASCII full text which is displayable and downloadable but not searchable, and gives examples of these. Highlights the full text databases which are being introduced by the H.W. Wilson Company

    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
    Academic and special research libraries in the US and Canada access on average 7,4 online systems. This probably doubles or triples when including CD-ROMs and locally loaded databases. Examines the many ways in which online versions of databases can vary on different systems. Discusses the differences of updating, dates covered, price, subfile structure, field subdivisions, content or inclusion, support features and system search features. Provides statistics on these differences

    Abstract
    Online offers the advantage over CD-ROM and locally loaded databases of being able to search several databases simultaneously. However, even when different databases have common fields, they may be named differently. This is improving, particularly throught he efforts of Mead Data Central and DIALOG. Discusses searching single databases; 2 ways in which online systems standardise fields; the lack of standardisation in the field tag SF=; Dialog's standardisation; generic field designs; standardisation of field content and NEXIS and uniform segmentation

    Abstract
    Observes that whether in academic, special, or public libraries or on commercial online systems, CD-ROM, the online catalogue, or the Internet, certain end user errors crop up repeatedly. Details the main errors, which include input errors, errors arising from confusion in the face of different interfaces and screen designs, Boolean logic errors, term errors, conceptual errors, and errors due to the fact that users do not read instructions. Concludes that systems must solve the trivial errors automatically, but user instruction librarians must help solve the more complex problems

    Abstract
    Considers some of the human factors in online interaction and Internet use. Discusses the following: users' need for help from libraries and librarians, given the difficulties people continue to have in accessing and using networked information; the challenge of user demands for speedy delivery of information and documents; the trend towards 'humanizing the net' through chat rooms and social agent interfaces (such as Microsoft's Bob); and the problems for libraries of users using the Internet for trivial or pornographic purposes
