    Abstract
    At Limburg Provincial Central Library and Information Service in the Netherlands the online public catalogue has been replaced by a new system, Foundation. The OPAC network was an automated version of the card catalogue, whereas Foundation has been developed entirely from scratch. The system runs on Windows software and assists even inexperienced users to formulate suitable search strategies. The system accepts online catalogue records from other sources and has attracted considerable intersts from several areas, including the publishing industry

    Abstract
    The Bradford OPAC is an experimental prototype OPAC, with a graphical user interface, based on the manifestation concept. It was designed to study some of the problems in catalogues where there are many versions of the same work or complex multipart works. In place of the main entry based approach of one complete record for each item, the OPAC groups together into sets items that are manifestations of the same work. Users are presented with shorter lists of different intellectual works. Items in a set can be sorted, searched and displayed according to user supplied criteria

    Abstract
    Library OPACs have long been the gateways between users and information. They present to users the achievements of library automation, and are the most widely available automated retrieval systems and the first that many user encounter. Current trends in OPAC design are toward a user oriented, individual information service which can meet the different needs of users with a variety of background and interests. Compared with the rather inactive, short term and general information service of conventional systems, this type of system focuses on active, long term and personalized service. Proposes a framework for the design of such an OPAC and discusses some recent developments in personalized information service

    Abstract
    This article first compares and contrasts the essential, fundamental differences between traditional and digital information mediums. It then reexamines the role of the online public access catalog (OPAC), refines the definition of library's catalog, and advocates the addition of Internet resources within the OPAC. Next, the article describes the building of the Alex Catalog, a catalog of Internet resources in the in the form of MARC records. Finally, this article outlines a process of integrating the futher inclusion of other Internet resources into OPACs as well as some of the obstacles such a process manifests.

    Abstract
    Briefly follows the debate concerning: the relationship between traditional library OPACs and the WWW; possible replacement of USMARC format with SGML; and the possible demise of OPACs that do not migrate to the WWW. Discusses the approach taken by the Text encoding Initative (TEI) in their use of a mandatory TEI header in their standard SGML application as the first since CIP to explore attaching bibliographic information to the item itself to assist cataloguing

    Abstract
    The Venice University Institute of Architecture has developed Easyweb, a software package to integrate its heterogeneous non-compatible bibliographic and multimedia databases, standardise access and create internal links, by transferring all existing OPAC applications to the Web. Features include importation of UNIMARC data, multiple window searching, multibase searching and special applications, e.g. circulation management. Easyweb is notable user friendly and has become the point of reference for OPACs in Italy

    Abstract
    Fac-Back-OPAC is a faceted back­ up OPAC. This advanced catalog offers features that compare favorably with the traditional catalogs for today's library systems. Fac-Back-OPAC represents the convergence of two prominent trends in library tools: the decoupling of discovery tools from the traditional integrated library system and the use of readily available open source components to rapidly produce leading-edge technology for meeting patron and library needs. Built on code that was originally developed by Casey Durfee in February 2007, Fac-Back-OPAC is available for no cost under an open source license to any library that wants to offer an advanced search interface or a backup catalog for its patrons.

    Abstract
    The library of the Cité des Sciences et de l'industrie attracts 4.000 visitors daily of whom 25% consult the GEAC system OPAC. Describes a 1992 survey consisting of online questions followed by an interview. The questionnaires were adapted from ones used in the UK and utilised OLIVE (Online Interactive Validation and Evaluation). While difficulties arose from users' inconsistency in their replies and failures to answer questions, it has become clear that subject access is unsatisfactory, sometimes because of mistyping by the searcher but also because of the vocabulary problems and lack of guidance in search strategies

    Abstract
    Subject access in the OPAC, as discussed in this article, is predicated on two different kinds of searching: subject (authority, alphabetic, or controlled vocabulary searching) or keyword (uncontrolled, free text, natural language vocabulary). The literature has focused on demonstrating that both approaches are needed, but very few authors address the need to integrate keyword into authority searching. The article discusses this difference and compares, with a query on the term garbage, search results in two online catalogs, one that performs keyword searches through the authority file and one where only bibliographic records are included in keyword searches.

    Abstract
    LIAS, the Pennsylvania State University's (Penn State) integrated interactive online system, provides for messaging by the user to inform library staff of errors found in bibliographic records. The message is sent by use of the OOPS command, and results in a printout which is used by processing staff for online catalog maintenance. This article describes LIAS, the use of the OOPS command, the processing of the resulting OOPS reports, an assessment of the effect of its use, and some speculation on the expansion of the LIAS message system for use in catalog maintenance.

    Abstract
    The aim of the research undertaken was to get to know the degree of implementation of discovery tools in university libraries in the Iberian Peninsula. It also allowed an initial evaluation of the facilities offered by the tools implemented. With regard to the presence of discovery tools we find a different situation in the two countries, with a higher degree of implementation in Spain. As for the behaviour of the discovery layers, the eight tools evaluated performed appropriately. Discovery tools represent a considerable advance. The combining of the library's catalogue and indexes to articles with other sources of information in a single unified interface is an unquestionable improvement. However, catalogues and databases still fulfil some purposes better than discovery tools. Libraries need to consider their clients when putting up on their websites the various tools for gaining access to contents.

    Abstract
    Enhancing content description of specialized resources, particularly astronomical resources, is a matter that is still unresolved in library and information science. In this paper, the authors outline deficiencies in some fields and elements of cataloging standards for description of historical astronomical resources, mainly star atlases and catalogs. Furthermore, they review their recent proposal of astronomical parameters for a better description and propose an approach for accommodating these parameters in the current criteria of MARC 21, the International Standard Bibliographic Description, and Resource Description and Access. Fourteen new parameters are considered, and recommendations are provided to standards developers for the addition of elements to accommodate attributes of celestial cartographic resources. This would improve bibliographic records for such resources in astronomical libraries' OPACs, which will have a beneficial effect on information retrieval.

    Abstract
    The primary objective of the present study was to exmine whether readers conducting bibliographic searches in ALEPH - Israel's research library network - tend to search only within the OPAC of the library within which they are working or whether they access the remote OPACs of other libraries. The ALEPH network has a dezentralized database. Therefore, it was possible to examine this question because each library has its own access code and each database can be searched separately. The data were collected by means of a one-page questionnaire lefr beside each terminal in the library of the Graduate School of Library and Archive Studies of the Hebrew University of Jerusalem during an entire academic years. results of analysis of the data collected in this survey are presented in 6 tables

    Abstract
    The growth and use of aggregator databases have presented libraries with both new opportunities for collection enhancement and new challenges of bibliographic control. How to integrate full-text electronic journal titles in unstable aggregator databases into a library's OPAC (Online Public Access Catalog) has been an especially taxing matter for libraries. This article describes the Hong Kong Baptist University Library's effort to integrate full-text electronic journal titles from three large, unstable aggregator databases into its INNOPAC-based OPAC. The library's electronic journal computer program (EJCOP) does this in a simple, direct, consistent, and accurate manner and addresses some of the issues elaborated in the January 2000 Final Report of the Task Group on Journals in Aggregator Databases of the Standing Committee on Automation of the Library of Congress Program for Cooperative Cataloging.

    Abstract
    Subject access to monographs through online public access catalogs (OPACs) has always been a major concern for large research and/or academic libraries. Academic library practice of providing subject access to monographs has proven inadequate, especially in the case of composite works. Many techniques have been proposed to enhance subject treatment of monographs in OPACs. This article briefly reviews these efforts in the past and presents the case of adding Tables of Contents as one of the Most useful and probably also one of the Most costeffective ways of improving subject access to Monographs in an academic environment.

    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.

    Abstract
    A relevancy-ranking algorithm for a natural language interface to Boolean online public access catalogs (OPACs) was formulated and compared with that currently used in a knowledge-based search interface called the E-Referencer, being developed by the authors. The algorithm makes use of seven weIl-known ranking criteria: breadth of match, section weighting, proximity of query words, variant word forms (stemming), document frequency, term frequency and document length. The algorithm converts a natural language query into a series of increasingly broader Boolean search statements. In a small experiment with ten subjects in which the algorithm was simulated by hand, the algorithm obtained good results with a mean overall precision of 0.42 and mean average precision of 0.62, representing a 27 percent improvement in precision and 41 percent improvement in average precision compared to the E-Referencer. The usefulness of each step in the algorithm was analyzed and suggestions are made for improving the algorithm.
    Content
    "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."
