    Abstract
    The development of company wide information systems (CWIS) will offer more comprehensive information systems to the academic users than present OPACs. Describes design consideration, technical aspects and organisational implications involved in this evolving technology. Lists possible facilities and services offered and examines responsibilities and liabilities when operating a CWIS

    The author presents the environment of the OPAC as a new revenue stream of high potential. He suggests that the abstracting and indexing community is neglecting this important source and suggests industry-wide adoption of open standards as a remedy

    Abstract
    In 1991 60,4% of Japanese university libraries had introduced computerized systems and 57,5% of these had computerized catalogues. In this context, discusses the following: subject searching in computerized catalogues; standardisation of OPACs, particularly as these are now available to a wide range of external users; and access to journal articles, especially in view of increasing journal purchase relative to books

    "Most Web search engines accept natural language queries, perform some kind of fuzzy matching and produce ranked output, displaying first the documents that are most likely to be relevant. On the other hand, most library online public access catalogs (OPACs) an the Web are still Boolean retrieval systems that perform exact matching, and require users to express their search requests precisely in a Boolean search language and to refine their search statements to improve the search results. It is well-documented that users have difficulty searching Boolean OPACs effectively (e.g. Borgman, 1996; Ensor, 1992; Wallace, 1993). One approach to making OPACs easier to use is to develop a natural language search interface that acts as a middleware between the user's Web browser and the OPAC system. The search interface can accept a natural language query from the user and reformulate it as a series of Boolean search statements that are then submitted to the OPAC. The records retrieved by the OPAC are ranked by the search interface before forwarding them to the user's Web browser. The user, then, does not need to interact directly with the Boolean OPAC but with the natural language search interface or search intermediary. The search interface interacts with the OPAC system an the user's behalf. The advantage of this approach is that no modification to the OPAC or library system is required. Furthermore, the search interface can access multiple OPACs, acting as a meta search engine, and integrate search results from various OPACs before sending them to the user. The search interface needs to incorporate a method for converting the user's natural language query into a series of Boolean search statements, and for ranking the OPAC records retrieved. The purpose of this study was to develop a relevancyranking algorithm for a search interface to Boolean OPAC systems. This is part of an on-going effort to develop a knowledge-based search interface to OPACs called the E-Referencer (Khoo et al., 1998, 1999; Poo et al., 2000). E-Referencer v. 2 that has been implemented applies a repertoire of initial search strategies and reformulation strategies to retrieve records from OPACs using the Z39.50 protocol, and also assists users in mapping query keywords to the Library of Congress subject headings."

    Abstract
    "Librarians should be careful to distinguish between their own abilities and those of their patrons when designing information systems, bibliographic instruction programs, and similar library services. The abilities of professionals may lead to preferences for sophisticated interfaces, complex instructional programs, or services that assumehigh levels of cognitive abilities, while their library patrons may find browse interfaces, simple point-of-need instruction, and basic services to be more appropriate to their levels of cognitive abilities

    Abstract
    Historically, library automation has focused attention on the automation of internal library processes, such as cataloging; however, a new generation of library automation systems intended for direct use by library patrons is emerging. These public-access computer systems are categorized and described. The types of public-access computer systems are: (1) catalog information systems, (2) electronic information systems, (3) information presentation systems, (4) instructional systems, (5) consultation systems, (6) information service and delivery systems, (7) conferencing systems, (8) integrative systems, and (9) end-user computing facilities. To be effective, these computer-based systems must be integrated with the traditional collections and services of libraries

    Abstract
    In an experiment to evaluate the effectiveness of a concept based computer tutorial for training OPAC users, it was found that Toronto University students who viewed the tutorial performed significantly better on search tasks than those who received no instruction. Reports the results of a second experiment to investigate the effectiveness of the computer tutorial. 15 students viewed the computer tutorial and another 15 students served as a control group and did not receive any instruction. Results showed no significant differences in performance between the students who viewed the computer tutorial and those who did not receive any instruction. Discusses the differences between the results of the 2 experiments in terms of the characteristics of the participants and the characteristics of the OPACs and relates these findings to the findings of other studies on concept based instruction and offer suggestions for future research

    Abstract
    It's clear that today's typical library users are Web-sawy and have very high expectations. Librarians need to offer interfaces on Web sites that match or exceed those found on the commercial Web. Paired with high-quality content that's selected and created by librarians, a state-of-the-art Web interface is a compelling destination for users.

    Abstract
    Diese Arbeit besteht im Wesentlichen aus zwei Teilen: Der erste Teil beinhaltet eine Einführung in den Begriff Web 2.0 und in die allgemeinen Rahmenbedingungen der zugehörigen technischen Entwicklungen. Des Weiteren werden exemplarische Techniken vorgestellt, die Web 2.0 zugeschrieben werden können sowie einige beispielhafte Anwendungen. Im zweiten Teil wird die Diskussion um Bibliothek 2.0 aufgegriffen, um anschließend näher auf Web 2.0 Techniken in Bibliothekskatalogen bzw. den OPAC 2.0 einzugehen. Verschiedene Techniken, die im OPAC 2.0 Anwendung finden können, werden diskutiert und zuletzt werden einige beispielhafte OPACs vorgestellt.

    Abstract
    One finding of the 2006 OCLC study of College Students' Perceptions of Libraries and Information Resources was that students expressed equal levels of trust in libraries and search engines when it came to meeting their information needs in a way that they felt was authoritative. Seeking to incorporate this insight into our own instructional methodology, Schaffer Library at Union College has attempted to engineer a shift from Google to Google Scholar among our student users by representing Scholar as a viable adjunct to the catalog and to snore traditional electronic resources. By attempting to engage student researchers on their own terms, we have discovered that most of them react enthusiastically to the revelation that the Google they think they know so well is, it turns out, a multifaceted resource that is capable of delivering the sort of scholarly information that will meet with their professors' approval. Specifically, this article focuses on the fact that many Google Scholar searches link hack to our own Web catalog where they identify useful book titles that direct OPAC keyword searches have missed.
