    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
    A summary of the findings of various evaluations of role indicators is given. In general, the results have been negative in that little real evidence for the value of the devices has been presented. The need for roles in various subject fields and in very large systems, is discussed. They can only by justified on purely ecomic grounds - if the added cost involved in their use is offset by substantial reduction in the amount of output screening that must be done by the end user

    Footnote
    Rez. in: JASIST 53(2002) no.4, S.321-322 (I. Fourie): "A substantial literature exists on artificial intelligence (AI) and expert systems in general, as well as in Library and Information Science (LIS). Many reports are over-confident and grossly exaggerate the power and potential of artificial intelligence (AI). This is especially true of the first phase of At, and to some extent also of the third phase that is stimulated by developments surrounding the Internet. The middle phase was mostly marked by disillusionment about the potential of Al and expert systems. The confusion around the promises made by AI and the lack of operational success, leaves managers of library and information services with the dilemma of distinguishing between worthwhile research reporting on operational projects and projects that exists only on paper or in the researchers' heads. It is very difficult to sieve between the two when working through the subject literature, and to distinguish between working technology/applications and wishful thinking. This might be one reason why working systems are sometimes ignored. According to Lancaster and Warner, library managers must also look much wider than the LIS literature to note new trends; this can, however, become a daunting task. Against this background the authors report on a study conducted with the support of the Special Libraries Association's Steven I. Goldspiel Memorial Research Grant. The objective of the study was to gain sufficient familiarity with the developments in Al and related technologies to make recommendations to the information service community on what can be applied, and what to expect in the near future. The intention therefore was to focus on systems that are actually operational, and systems that hold potential for the future. Since digital libraries seems an inevitable part of our future, applications concerning them features strongly in the final recommendations. The scope of AI in Library and Information Science depends on the interpretation of the concepts artificial intelligence and expert systems. "If a system has to `behave intelligently' (e.g. make inferences or learn from its mistakes) to qualify as having AI, few such systems exist in any application. On the other hand, if one accepts that a system exhibits AI if its does things that humans need intelligence to do, many more systems would qualify" (p. 107). One example is the field of subject indexing. The same would apply if a more relaxed definition of expert systems is applied as a system that "can help the non-expert perform some task at a level closer to that of an expert, whether or not all the essential components are in place" (p. 107). Most of the AI literature relevant to libraries falls in the field of expert systems. Lancaster and Warner identify (p. 6) expert systems as " a branch of artificial intelligence, even though very few expert systems exhibit true intelligence.""

    Abstract
    Computer have been used in 2 areas of printed index production: to sort entries and fromat printed indexes, and to derive a series of index entries from a minimum intellectual input. Computer indexing enables more indexing terms to be used as well as weighted terms, links and roles. Interest in automatic indexing peaked in the mid-1960s and has since declined. Interest in machine-aided indexing concentrates on using the computer for on-line display or for indexing by extraction. Computers have also made possible the implementation of retrieval systems without indexing-free text systems. Considers future prospects and needs

    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
    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
    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
    F.W. Lancaster's work has been immensely influential in library and information science. He has written on indexing and information system evaluation, and has been looked to as a pioneer in many areas. Here he describes precision and recall, the two most fundamental and widespread measures of information retrieval effectiveness.

    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
    Reports results of an analysis of 205 randomly selected records from the OCLC OLUC, to test the assumption that online catalogues have greatly improved subject searching capabilities, over card catalogues, by making other fields in the records searchable as subject access points (SAPs). Results showed considerable overlap (duplication) among the SAPs provided by the title, subject heading and classification number fields. On average, little more than 4 unique, unduplicated access points were found per record. Where title and classification number fields do add some access points not provided by subject headings, the increase is less than many librarians might be expected. Suggests that OPACs might outperform catalogues more in precision than in recall by allowing greater discrimination in searching; terms from different fields may be combined; titles offer greater specifity; searches can be limited by date, language or other criteria
