    Abstract
    The quality of large catalogs is uneven and often low, but this issue is underrated and understudied. Library catalogs often fail to communicate correct and clear information to users and their low quality is not simply due to faults, duplications, and so on but also to unwise cataloging standards and policies. While there is plenty of uncontrolled information about books and other publications, the need for good-quality bibliographic information is apparent and library catalogs may provide a trustworthy map of the publishing output, with full control of editions, works, authors, and so on and effective navigation functions, which are lacking in today's information-rich environment.

    Abstract
    Argues that in library cataloguing and for optional functionality of bibliographic records the indexing of fields and subfields should follow a uniform approach. This would maintain effectiveness in searching, retrieval and display of bibliographic information both within systems and between systems. However, a review of different postings to the AUTOCAT and USMARC discussion lists indicates that the indexing and tagging of cataloguing data do not, at present, follow a consistent approach in online library systems. If the rationale of cataloguing principles is to bring uniformity in bibliographic description and effectiveness in access, they should also address the question of uniform approaches to the indexing of cataloguing data. In this context and in terms of the identification and handling of data elements, cataloguing standards (codes, MARC formats and the Z39.50 standard) should be brought closer, in that they should provide guidelines for the designation of data elements for machine readable records

    Abstract
    A discussion document produced following a meeting the Users of Book Industry Standards (UBIS) Bibliographic Standards Working Group at the University of London as part of a project to consider the Survey on the use of UK-MARC by Russell Sweeney published in 1991 by the British Library National Bibliographic Service. Considers the suitability, or otherwise, of the UKMARC format for use in OPACs. Summarizes the issues involved, discussing: the UKMARC exchange format, tagging and coding structure (record complexity, analytical entries, non filing indicators), data content (statements of responsibility, main versus added entry) and records standards

    Abstract
    Makes a proposal for the optimization of first generation online catalogues which tries to unify the different institutional projects for the establishment of simplified ISBD standards and MARC formats, as well as the results of occasional studies and researches on cataloguing codification. Offers a feasible solution, for immediate application, for a definitive transition from card catalogue to automated catalogue

    Abstract
    The computer technology has considerable potential for better and more efficient management of knowledge and information sources. It is possible to provide easy, integrated and straightforward access to works of knowledge appearing in different expressions, editions, and manifestations (i.e., to bibliographic families). The online environment requires that the bibliographic record, as the surrogate for works of knowledge, should be restructured to provide users with a high-quality finding, identifying and collocating bibliographic tool. Unlike the existing flat structure, the multi-level structure of the Work Record would provide catalog users with the ability to discover if a work has been published/represented in different editions and manifestations and if there is any relationship among different works in a catalog or an the Internet. A similar structure for the Author Record would provide better access to different works by an author or about an author. A new structure for the bibliographic record is suggested through an analysis and categorization of the different relationships that exist in the bibliographic universe. A prototype catalogue developed based an the new structure (available an the Internet at: http://wilma.silas.unsw.edu.au/ students/rfattahi/super.html) illustrates the ability of providing multi-level, yet easy access to voluminous works and voluminous authors. Furthermore, the prototype catalog provides a clearer picture of bibliographic families and helps OPAC users decide an specific editions, manifestations, or items related to a specific work.

    Abstract
    The study Functional Requirements for Bibliograpbic Records (FRBR) was commissioned by IFLA and published in 1998. It defines the core functions of a catalogue (and bibliographic records) as a gateway to information. For that purpose an abstract entity-relationship model of a catalogue is proposed. The FRBR model is revolutionary. The (computer) catalogue is not seen as a sequence of bibliographic records and a replica of the traditional card catalogue, but rather as a network of connected entities, enabling the user to perform seamlessly all the necessary functions. So far there has been some theoretical discussion of the model and some limited experiments, but there is a lack of research in how to implement this theoretical model in practice, in new-generation catalogues. In this paper some reactions to the model are analysed. The main focus is an consequences of the model for the OPAC interface design, particularly the searching functionality and display of results.

    Abstract
    Surveys the status of catalguing practice in university libraries in 3 Asian developing countries, Pakistan, Malaysia, and Saudia Arabia. Examines the extent of the usage of international cataloguing tools such as cataloguing codes (AACR, ISBD), classification schemes (DDC, LCC) and subject heading lists (Sears, LCSH). Results indicate that there is an overall uniformity in the use of such tools, with a trend towards automation of cataloguing services with more access points for catalogue searching. Online catalogues are also replacing all traditional catalogue forms (card, printed, and microform). Findings show that, in using information technology in technical services, Malaysian university libraries are more advanced than those of Pakistan and Saudi Arabia

    Abstract
    Many experts have proposed an evolution toward "next generation catalogs," whose main features are partly inspired by commercial websites such as Google or Amazon. This article examines pros and cons of this integration. It also aims to show how a qualitative approach helps to broaden understanding of web communication mechanisms. After discussing some examples of "next generation catalog" features, I analyze the interface of an online catalog responding to different users' information needs and seeking behaviors. In the conclusion I suggest that the right approach to integration is a "translation" (not a "copy and paste") between commercial and library logics.

    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
