    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
    Discusses ways of applying MARC Field 856 (Electronic Location and Access) to authority records in online union catalogues. In principle, each catalogue site location can be treated as the electronic record of the work concerned and the MARC Field 856 can then refer to this location as if it were referring to the location of a primary record. Although URLs may become outdated, the fact that they are located in specifically defined MARC Fields makes the data contained amenable to the same link maintenance software ae used for the electronic records themselves. Includes practical examples of typical union catalogue records incorporating MARC Field 856

    Abstract
    In this paper I describe a conceptual design of a bibliographic retrieval system that enables more thourough control of bibliographic entities. A bibliographic entity has 2 components: the intellectual work and the physical item. Users searching bibliographic retrieval systems generally do not search for a specific item, but are willing to retrieve one of several alternative manifestations of a work. However, contemporary bibliographic retrieval systems are based solely on the descriptions of items. Works are described only implcitly by collocating descriptions of items. This method has resulted in a tool that does not include important descriptive attributes of the work, e.g. information regarding its history, its genre, or its bibliographic relationships. A bibliographic relationship is an association between 2 bibliographic entities. A system evaluation methodology wasused to create a conceptual schema for a bibliographic retrieval system. The model is based upon an analysis of data elements in the USMARC Formats for Bibliographic Data. The conceptual schema describes a database comprising 2 separate files of bibliographic descriptions, one of works and the other of items. Each file consists of individual descriptive surrogates of their respective entities. the specific data content of each file is defined by a data dictionary. Data elements used in the description of bibliographic works reflect the nature of works as intellectual and linguistic objects. The descriptive elements of bibliographic items describe the physical properties of bibliographic entities. Bibliographic relationships constitute the logical strucutre of the database

    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
    As a standard set of rules, AACR2 has received much attention in the literature of descriptive cataloguing. Considers that despite this extensive literature, an important aspect of the code, namely its relevance to the online environment, has not received much attention, particularly in terms of empirical research. Notes however that there is a general criticism that AACR2, being based on manual systems, does not correspond effectively to the online environment. From a review of the literature concludes that while the advent of online catalogues has changed both the internal structure and external appearance of library catalogues, a mojority of writers consider that radical changes in the code are impossible and undesirable in the near future, owing to various factors such as the belief that that MARC format is not conductive to radical change and the large size of existing catalogues created according to the current rules

    Abstract
    The chief of cataloguing policy and support office at the LoC presents her views on the usefulness of conceptual modelling in determining future directions for cataloguing and the MARC format. After describing the evolution of bibliographic processes, suggests usign the entity-relationship conceptual model to step back from how we record information today and start thinking about what information really means and why we provide it. Argues that now is the time to reexamine the basic principles which underpin Anglo-American cataloguing codes and that MARC formats should be looked at to see how they can evolve towards a future, improved structure for communicating bibliographic and authority information

    Abstract
    Currently, few resources exist to guide libraries in the cataloguing of community information using the new USMARC Format for Cammunity Information (1993). In developing a community information database, Queens Borough Public Library, New York City, formulated their own cataloguing procedures for applying AACR2, LoC File Interpretations, and USMARC Format for Community Information to community information. Their practices include entering corporate names directly whenever possible and assigning LC subject headings for classes of persons and topics, adding neighbourhood level geographic subdivisions. The guidelines were specially designed to aid non cataloguers in cataloguing community information and have enabled library to maintain consistency in handling corporate names and in assigning subject headings, while creating database that is highly accessible to library staff and users

    Abstract
    The Bayerische Staatsbibliothek acting on behalf of the Consortium of European Research Libraries (CERL) was responsible for the preparation of this report under a contract agreed with the Commission of the European Communities Directorate General XIII as part of their Libraries Programme. The report considers the feasibility of the application of UNIMARC to multinational databases, and was based on a comparison of machine-readable bibliographic records in the UNIMARC format from 6 different national sources. Some are conversions from other formats, while others are 'native' UNIMARC records. The records are of books of the hand press period, that is, from the time of Gutenberg to about 1830

    Abstract
    It is assumed that the conceptual structure of bibliographic records is based on the knowledge of user needs. In applying the entity-relationship model to the library catalogue the authority file and bibliographic records can be viewed as attributes, and the links between records and elements as relationships. Outlines the bibliographic relationships of the UNIMARC format, the analysis of hierarchical relationships carried out by Goosens and Mazur-Rzesos, and the typology of bibliographic documents established by McCallum. Presents 7 types of relationships developed by Tillet and gives results of an empirical study carried out to establish the extent and features of bibliographic relationships in the computerized catalogue of the Library of Congress

    Abstract
    The topic was the implementation of format integration which will enalbe materials which have some aspect of seriality but could also be defined as another format, to be catalogues as both. An update of OCLC's format integration was given. The 1st phase, encompassing the changes to fields 010-8XX, will be complete by the end of 1994. The 2nd phase, which will contain changes to the 007 and 008 fields and the introduction of the 006 field, is scheduled for completion by the end 0f 1995. Local system vendors were supportive of format integration and changes to relevant programs were underway in preparation for implementation. In a discussion of conversion of pre-format integration records to format integration MARC it was felt that adequate staff and funding would not be available for massive conversion projects and that only selected records would be converted

    Abstract
    Electronic documents are creating new services and generating new demands, with consequent impacts on the means of transmitting knowledge, international standards and democratisation of access. Universal bibliographic control depends on common rules for bibliographic description and format to ensure compatibility and exchange. In addition to ISBN and UNIMARC for cataloguing, Z39.50 allows searching of heterogeneous databases and SGML makes cataloguing in publication a reality. Such developments must be based on knowledge of what users want and their real search and consultation practices, not what the system devisers have the technology to create

    Abstract
    Catalogues have evolved from lists of physical items present in particular libraries into computerized access and retrieval tools for works dispersed across local and national boundaries. Works themselves are no longer constrained by physical form yet cataloguing rules have not evolved in parallel with these developments. Reanalyzes the nature of works and their publication in an approach based on object oriented modelling and demonstrates the advantages to be gained thereby. Suggests a strategic plan to enable an organic transformation to be made from current MARC based cataloguing to object oriented cataloguing. Proposes major revisions of MARC in order to allow records to maximize the benefits of both computerized databases and high speed data networks. This will involve a fundamental shift away from the AACR philosophy of description of, plus access to, physical items

    Abstract
    Evaluates current research into bibliographic relationships sparked off by B.B. Tillett's taxonomy of bibliographic relationships (LRTS 35(1991) no.4, S.393-405) and R.P. Smiraglia's taxonomy of the derivative bibliographic relationship (PhD dissertation, Chicago Univ., Graduate Library School, 1992). These researches provide the context for a discussion of recent research and standards work. Reevaluates research on the sequential relationship drawn from work conducted on periodicals and the implications of that research is applied to cataloguing system design. Evaluates the conceptual designs proposed by researchers such as G.H. Leazer and M. Gorman's and uses them in a critique of the USMARC format for bibliographic description

    Abstract
    Presents a general introduction to the form and functions of the Text Encoding Initiative (TEI) headers and explains their relationship to the MARC record. The TEI header's main strength is that it documents electronic texts in a standard exchange format that should be understandable to both librarian cataloguers and text encoders outside of librarianship. TEI gives encoders the ability to document the the electronic text itself, its source, its encoding principles, and revisions, as well as non bibliographic characteristics of the text that can support both scholarly analysis and retrieval. Its bibliographic descriptions can be loaded into standard remote bibliographic databases, which should make electronic texts as easy to find for researchers as texts in other media. Presents a brief overview of the TEI header, the file description and ways in which the TEI headers have counterparts in MARC, the Encoding Description, the Profile Description, the Revision Description, the size and complexity of the TEI header, and the use of the TEI header to support document retrieval and analysis, with notes on some of the prospects and problems

    Abstract
    Presents a view on the work of the Functional Requirements for Bibliographic Records Study Group on behalf of the Anglo-American cataloguing tradition. The study is examining the fundamental aspects of record design using the entity-attribute-relationship model to link data elements to the function that a user can perform while accessing a bibliographic record. The data and functions are being linked by UNIMARC fields
