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.

Reports results of a study that examined Library of Congress topical subject headings and subdivisions in a large bibliographic database. Creation of a new machine-readable authority file of topical subdivisions and enhancements to the existing subject authority file are recommended to assist in assignment and validation of subdivided headings.…

Describes the "Rutgers Inventory of Machine-Readable Texts in the Humanities" that provides bibliographic information through RLIN (Research Libraries Information Network) for electronic texts in the humanities. Highlights include adaptation of MARC format; access points; search strategies; and unresolved issues in the bibliographic…

Describes a project at the Princeton University libraries that converted the pre-1981 public card catalog, using digital imaging and optical character recognition technology, to fully tagged and indexed records of text in MARC format that are available on an online database and will be added to the online catalog.

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 the evolution of computerized information storage and retrieval from its mid-nineteenth century beginnings in theoretical works on logic by George Boole, to the applications of Boole's logic to switching circuits by Claude Shannon in the 1930s, to the development of coordinate indexing by Mortimer Taube in the 1940s and 1950s. (Contains…

Describes surveys of catalogers, geo-science faculty, and graduate students that explored the provision and use of subject access through geologic or geographic names. Strategies for improving such access through cataloging techniques, user education, and the use of advanced technologies are discussed. (21 references) (CLB)

Proposes a rationale to be used in comparing and evaluating alternative library computer catalogs, based on varieties of bibliographic data processed, kinds of indexes constructed, and desired search strategies. A glossary of terms related to computerized catalogs is appended. (Author/CLB)
