    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
    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 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
    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
    Myriad new information resources are available to contemporary library users. While print remains the foundation of most collections, libraries are also beginning to provide access to an array of bibliographic, numeric, and full-text databases. As more and more information is produced in electronic form and presented at computer workstations, the library catalog is being given an expanded role. The expanded catalog will play a crucial part in organizing information in electronic libraries, and in providing navigational assistance to library users. Like the traditional card catalog, the expanded catalog will not only lead to specific items or groups of sources, but also will provide connections to related materials. These connections will uses standard data elements to link the results of a search in one database with related material in another. For example, links will show local library holdings of sources in citation databases. Cornell University's Mann Library serves the College of Agriculture and Life Sciences, the College of Human Ecology, and the Division of Biological Sciences. As part of electronic library development, Mann staff have been analyzing issues involved in making it possible for Agricola and BIOSIS users to see, automatically, which of their retrieved citations are from sources available in the Cornell libraries. Samples of citations from Agricola and BIOSIS were drawn, and data elements present in these records were compared with bibliographic records of the library's holdings. In some cases, links would be provided by ISSNs. The study shows, however, that the presence of standard identifiers such as ISSN, USBN, or CODEN cannot be assumed, and other linking algorithms must be developed. This article presents study results, provides an overview of several linking systems, and identifies some of the difficulties caused by lack of standardization between different bibliographic databases. It is clear that the concept of an expanded catalog will require not only links between information resources but agreements among information professionals on standard data elements.

    Abstract
    Describes the technical aspects of a feasibility study to test a new concept in bibliographic control based on the manifestations of a work. Conventional catalogues are based on the main entry principle which follows from the concept that there should be 1 main entry for each work. The Bradford OPAC project, at Bradford University, UK, aimed to develop a new type of hierarchical bibliographic record structure to cope with the problem of applying the main entry principle to multiple cataloguing records which are manisfestations of the same work. The project involved the storage of MARC data sets of bibliographic records, taken from the Bradford University Library OPAC and the OCLC WorldCat database, in a relational database (MS Access) on a PC. This was then used for an experimental Windows based OPAC, to evaluate the overall success of the idea and any problem areas identified with a view to a more substantial study. The project also aimed to test whether intelligent and responsive software, using a graphic user interface and based on sets of manifestations, could provide a better route to information than a display based on a single work

    The Sterling C. Evans Library at Texas A&M University has provided a test site for OCLC's FirstSearch service. FirstSearch provides OCLC access by subject and keyword. Evaluates FirstSearch as a bibliographic tool according to user success and the ability to identify relevant material better than conventional tools

    Abstract
    This article describes a few of the MELVYL system's search features that are not generally known, even to frequent searchers, so that readers can appreciate how difficult it is to discover these features without being told. The author postulates that users who view the MELVYL system as a reference tool instead of a catalog are willing to spend more time exploring the advanced system features and are more tolerant of its shortcomings as a library catalog
