    Abstract
    In the monastic library of the Middle Ages, the librarian was essentially a curator, a preserver of collections. For most of history libarians were little more than custodians. The idea of a librarian as a provider of services rather than a collector or preserver of materials, did not emerge until late in the 19th century. Computer and telecommunications technologies have revolutionized the library and greatly expanded the horizons of the librarian. Discusses the ways in which technology has affected the library profession and discusses the role of the librarian in the future. The librarian will increasingly become an information intermediary or information consultant and some will be knowledge engineers involved in the design and construction of information systems and in electronic publishing

    Abstract
    Based partly on chapters in a forthcoming book 'Technology and Management in Library and Information Sciences' by F.W. Lancaster and B. Sandore. Some inportant functions of a research library operating largely in a networked digital environment are illustrated. The ability of artificial intelligence and expert system technologies to contribute to these functions is discussed, in the light of a report from the American Association for Artificial Intelligence, as well as experiences with these technologies in the library world and elsewhere

    Abstract
    A review of developments in electronic publishing over the last 25 years is followed by a report on a survey conducted, with directors of university libraries and other academic administrators, to determine attitudes toward a networked electronic approach to the publishing of research articles. A major conclusion is that academic administrators do not now consider the academic community well equipped to undertake an enterprise of this kind and would not give it high priority in the allocation of university resources

    Abstract
    An overview of levels and approaches in the evalution of knowledge-based systems is presented. There is a need for empirical studies using objective criteria in advance of completing the technical evaluation of such systems. A methodology for this type of evaluation developed for a particular knowledge-based indexing system is presented. It is suggested that the proposed study may serve as a model for the design of any evaluation in which the results of existing intellectual procedures are compared with results achieved when these procedures are aided by use of an appropriate expert system

    Abstract
    Reports an unobtrusive study of the ability of professional librarians to deal with factual questions conducted at the Milner Library, Illinois State University. Standards were recruited to pose questions for which answers were known, to 19 librarians in 5 departments. In all, 190 test incidents (10 questions for each of the 19 librarians) were used. Librarians were evaluated on the accuracy of the responses given and on their responsiveness and helpfulness, as judged by the student proxies. Describes the methods used in the study, including the accuracy and attitude scales developed, presents the major results, and makes suggestions on the follow-up action that seems appropriate after a study of this kind has been performed

    Abstract
    Reports on a study which collected a sample of 846 scientific research papers published in 1992 and tests 3 hypotheses on the relationship between research collaboration and interdisciplinarity. Results showed significant differences in degrees of interdisciplinarity among different levels of collaboration and among different disciplines. Collaboration contributed significantly to the degree of interdisciplinarity in some disciplines and not in others. Uses a survey that asked authors about their form of collaboration, channels of communication and use of information. The survey provides some qualitative explanation for the bibliometrics findings. Discusses the perspective of scientist-scientist interaction, scientist-information interaction and information-information interaction

    Abstract
    Two years ago the author gave a keynote talk at the Essen Symposium that suggested that technology has lulled librarians into a false sense of security and that there is no real evidence that the increasing use of technology has improved library services at all. This talk carries this theme one stage further, suggesting that technology may actually encourage mediocrity in library and information services

    Abstract
    The results of 35 searches performed by users (end users) of an academic library (Illinois Stae University, Milner Library) in the ERIC databases on CD-ROM were compared with the results for the same topics achieved by an experienced education librarian and by a team of librarians. Recall ratios, precision ratios, and novelty ratios were calculated. Results show that the users, all faculty members or graduate students, found only about a third of the really important items. Suggests that library users are frequently misled into thinking that CD-ROM databases are easy to use and that the 'technology' guarantees satisfactory results.

    Abstract
    Reports results of an evaluation of 2 expert systems designed for use in library reference services: ReferenceExpert (RE), developed by Houston University; and SourceFinder (SF), developed by Illinois University at Urbana-Champaign. The test group consisted of 60 graduate students at the initial stage of an intermediate level reference course. The evaluation involved test questions already used in an earlier study (College and research libraries 52(1991) no.5, S.454-465). Results indicated that: there was no significant difference between RE and SF students in the confidence they expressed regarding understanding of their test questions; no significant correlation was found between confidence in understanding the question and success in selecting appropriate sources; only 1/5 of the students agreed that the system they used could be considered 'intelligent'; the majority did not consider the system they used to be 'competent'; almost half agreed that the subject categories provided by the menus were too broad; a little more than half wer not satisfied with the information sources selected by their system; significantly more RE users than SF users agreed that they found the menu interface useful; and a keyword search capability was the feature most often mentioned as a needed system enhancement. Overall results indicated that current expert systems for the selection of reference sources cannot perform as well as experienced subject oriented reference librarians

    Abstract
    Reviews the trend away from a paper based society and towards an electronic society: with the advent of computers, electronic mail, computer conferencing, electronic invisible colleges, and the application of computers to libraries and information networks, and to publishing, with the production of electronic media. Forecasts the advent of the electronic library and the electronic librarian, the decline in the use of present day libraries, technical and library services, and the enhanced and extended role of librarians in the new situation. Predicts the eventual demise of the traditional library with the exception of non research libraries but the enhanced value of the librarians as an information specialist
