Presents the conceptual design of a full-scale bibliographic database that includes bibliographic, authority, holdings, and classification data and is based on entity-relationship modeling. MARC format, AACR2 (Anglo-American Cataloging Rules) compatibility, and normalization and efficiency are discussed. (Author/LRW)

A hierarchical extension to the American National Standard for Bibliographic Information Interchange on Magnetic Tape is defined and described. The accommodation of the extension within the existing standard is discussed, modifications to the existing standard are proposed, and applications of the hierarchical format are presented. (21 references)…

Describes a study that examined the ability of the dBase database management system to perform secondary key retrieval on multivalued data items. The results are presented as time cost relative to the number of matching records, and situations in which a different management system might be appropriate are identified. (CLB)

Describes Structured Query Language (SQL), the result of an American National Standards Institute effort to standardize language used to query computer databases and a common element in second generation database management systems. The discussion covers implementations of SQL, associated products, and techniques for its use in online catalogs,…

Describes the planning, development, implementation and impact of online information systems at three academic libraries. Some of the issues discussed include the campus computing environments, factors affecting the selection of databases and search systems, the impact of the system on library staff and users, and future considerations. (CLB)

Describes the object-oriented paradigm (modeling a system by the objects that constitute it and the class relationships between objects) and presents examples of its application to automated library systems, including a model of a hierarchical and relational bibliographic database. Advantages and disadvantages of the paradigm for information…

Discusses categorization of MARC records, noting problems which arise because formats have not been defined as distinct sets of content designators. Bibliographic and authority record formats, merging of formats into single format, removal of inconsistencies, and criteria for identifying categories of records are considered. Thirty-one references…

Describes PCBIS, a database program for MS-DOS microcomputers that features a utility for automatically converting online public access catalog search results stored as text files into structured database files that can be searched, sorted, edited, and printed. Topics covered include the general features of the program, record structure, record…

A microcomputer database management system is used to create and index profiles of individual college faculty and to monitor their expertise (curricular, research, professional subject interests) and trends in university programs. The faculty profile is useful in improved referrals, collection development activities, staff orientation, and public…

Describes a survey of library systems and software vendors that examined the sources, management, and use of authority records in their systems and the functions of an authority control module within an integrated system. Several tables and graphs offer summaries and comparisons of vendors' offerings and capabilities. The questionnaire used is…

Describes an integrated online library system developed at the University of California at Los Angeles (UCLA) which incorporates a number of database management features that enhance efficiency, for record retrieval and display. Design features related to record storage and retrieval and the design of linked files are described in detail.…

Each of three articles describes an academic library's online catalog that includes locally created databases. Topics covered include database and software selection; systems design and development; database producer negotiations; problems encountered during implementation; database loading; training and documentation; and future plans. (CLB)

Integrating machine-readable data files and microcomputer software (combined as MRDF) into traditional library and information services by incorporating a MARC format for them into the bibliographic networks will increase access to those materials. Standards for their bibliographic control have been developed and progress is being made in their…

Describes textual database queries in the humanities based on poststructuralist theories and experiences with the ARTFL (American and French Research on the Treasury of the French Language) database. The use of computers for literary research and text interpretation and analysis is considered. (Contains nine references.) (LRW)

Investigates methods of compressing headings identified by MARC subfield codes to reduce the size of browsable displays. An argument is made for sorting subdivisions by a conceptual, rather than an alphabetical, approach to present efficient browsable displays and relieve the user of the burden of data organization.
