    Abstract
    A bibliographic relationship is an association between two or more bibliographic items or works. In an effort to provide the theoretical base for a conceptual model of the library catalog, past and future, the bibliographic relationship is examined here in detail. In this first of a series of reports, a taxonomy of bibliographic relationships is derived from an analysis of cataloging rules and types of bibliographic items.

    Abstract
    A comparatively informal cooperative arrangement among five Indiana libraries sharing Indiana State University's NOTIS system is described. In contrast to groups that were planned as consortia and that have formal governance and staff, the ISU service group, which includes the libraries of Indiana State University, Rose-Hulman Institute of Technology, St. Mary-of-the-Woods College, University of Southern Indiana, and Vincennes University, has evolved over a period of five years as opportunities for funding have become available

    Abstract
    Briefly discusses the role of search languages in information retrieval and broadly groups the search languages into 4 categories. Explains the idea of definite clause grammars and demonstrates how parsers for Boolean logic-based search languages can easily be developed. Presents a partial Prolog code of the parser that was used in an object-oriented bibliographic database management system

    Abstract
    Reports on an analytical study to examine the cataloguing rules in AACR2 to reveal practices for indicating bibliographic relationships in cataloguing records and identify types of relationships. Relationships defined and investigated were: equivalence; derivative; descriptive; whole-part; accompanying; sequential; and shared characteristic relationships.Each type of bibliographic relationship has had several linking devices used to connect bibliographic entities. The technology available to create and maintain a catalogue has greatly influenced the types of linking devices included in the catalogue and prescribed in cataloguing rules

    Abstract
    Since the closing of the Sterling C. Evans Library author/title card catalog on march 6, 1989, librarians have observed a number of patrons who continued to use that catalog, even though NOTIS, the OPAC offered more comprehensive and current access to library holdings. To determine the reasons for this use, the authors prepared a one-page questionnaire, focusing on the users' preference for an inadequate card catalog in an environment which offers a superior OPAC. Card catalog patrons were then surveyed in order to gather data and build a user profile. Survey results were tabulated and analyzed, revealing the underlying reasons for users' preference for the card or online catalog. Conclusions will provide direction for improvements in users' access to online catalogs

    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
    Librarians in the United States always seem to be trying to reduce their costs and share resources through various centralized or cooperative endeavors. Early cooperative cataloging efforts, prior to 1967 when the MARC format made its appearance and automation took off, clearly recognized the need to create a shared national resource of bibliographic records. Yet, the dreams of cataloging it once for all turned into nightmares over and over as many schemes were tried and failed. However, some schemes succeeded and millions of items were cataloged through these early efforts. The promise of our preliminary steps in cooperative cataloging during the pre-automation era sparked our imaginations and raised our hopes for the future.

    Abstract
    This article reports the findings of an experiment using a simulated title pages, author surnames, and title words, one-third of which were selected by each of the 3 authors, to determine the frequency of one-screen displays when used to search for known items in an implied Boolean retrieval system. Searches comprising surname plus one significant title word produced one-screen displays 78% of time; surname plus 2 words 97% of the time; and surname plus 3 words 98,5%. Three quarters of the significant words were nouns

    Abstract
    The work begins by reviewing publications on the use of optical-disc technology in cataloging departments. This section includes descriptive information on specific products and comparative considerations on the value of the CD genre. Most commentary to date seems to find cost advantages to the optical format for smaller libraries but fewer attractions for larger institutions who would lose online immediacy. An outline of the design and results of the OCLC test follows along with various tables showing the class makeup of the overall sample, the hit-rate for the two vendors, and other data. Most of the sample consisted of English-language titles that would support the general academic mission of a variety of disciplines. Well over 90% of the titles searched had MARC records on discs within two issues or three months. Although concluding that departments acquiring over 5000 titles per year may find online utilities more effective, the article still urges a careful analysis of laser cataloging products with a variety of acquisition samples and for a variety of libraries.
