Research report on analytical review of catalog use studies by Karen Markey( Book )

4 editions published in 1980 in English and held by 14 WorldCat member libraries worldwide

This review takes a critical approach in summarizing and evaluating the methodology and scope of catalog use studies, with emphasis on the subject approach to card catalog searching. Subject access is defined in this report; however, the process of subject searching, described repeatedly in library literature, has been based upon common sense understanding rather than systematic observation. The findings of catalog use studies are classified into: (1) generalizations on the physical format of the catalog, information found on the cards, catalog searchers' educational level or area of expertise, and reference assistance; (2) generalizations specific to subject searches, user characteristics, and the physical structure of the catalog; and (3) generalizations specific to known-item searches and nonstandard information, failure at the catalog, and author-title information. The major reviews of catalog use studies and their methods are also covered. A bibliography of catalog use studies and a cited author index are provided. (Author/RAA)
Research report on field, subfield, and indicator statistics in OCLC bibliographic records by Thomas Butler Hickey( Book )

2 editions published in 1981 in English and held by 9 WorldCat member libraries worldwide

The statistics that are presented are based on a one percent systematic sample of the oclc online union catalog as of January 1980. Detailed data were collected on the use of fields, subfields, indicators in bibliographic records, and on the co-occurrence of fields within bibliographic records. The sample used for the study was obtained by extracting all records with an oclc control number ending in 44. For each category of this report, the statistics are grouped by format: monographs, serials, audiovisuals, sound recordings, music scores, maps, manuscripts, and cumulative bibliographic files. These statistics should be useful for estimating file growth, selecting subsets of records for local catalogs, and for designing bibliographic record data bases. (Author/RAA)

Pilot test of the Online Public Access Catalog Project's user and nonuser questionnaires by Karen Markey( Book )

2 editions published in 1982 in English and held by 4 WorldCat member libraries worldwide

This report describes the pilot data collections and post-questionnaire interview activities of the Council on Library Resources (CLR)/Online Computer Library Center (OCLC) Online Public Access Project. The background of the project is briefly described, the purpose and adminstration of the post-questionnaire interviews are outlined, and pilot data collection activities are reviewed. The procedures of both the pilot data collection and the pilot data analysis phases of the project are then discussed. Two data tables accompany the text. Among the eight appendices to the report are guidelines for conducting post-questionnaire interviews, library catalog user and nonuser interview schedules, lists of user and nonuser questionnaire problems, the pilot test data collection manual, and the actual study data collection manual

Research report on an overview of a proposed monitoring for the large-scale, network-based OCLC on-line system by Wayne D Dominick( Book )

1 edition published in 1980 in English and held by 1 WorldCat member library worldwide

This report addresses the critical importance of measuring and evaluating information systems functioning within computer network environments. The focus is on the significant benefits associated with using automated monitoring as the primary information system measurement mechanism within such computing architectures. The large scale, network-based, state-of-the-art oclc online system is utilized as the information system environment in support of these research and development activities. Within this environment an overall structure for a generalized, automated monitor design is proposed. Monitoring specifications are illustrated at the network supervisor level, the applications processor level, and the database processor level within the oclc system network architecture. The monitoring concepts, techniques, and parameters presented within this report represent a strong foundation for information system measurement, analysis, and evaluation. When combined with complementary measurement facilities such as controlled benchmarks and synthetic programs, simulation models and controlled user interface experiments, a total comprehensive methodology for information system evaluation can be realized. The principles of automated monitoring have proven their extensibility and generalizability across numerous types of information systems. It is concluded that automated monitoring should be viewed as an essential self-measurement capability within all future information system designs. (Author/RAA)

Research report on subject heading patterns in OCLC monographic records by Edward T O'Neill( )

2 editions published in 1979 in English and held by 0 WorldCat member libraries worldwide

This investigation examines the characteristics of subject headings occurring in cataloging records. The study analyzes a sample of 33,455 monographic records taken from the OCLC database. The sample contained a total of 50,213 subject headings, 94% of which were Library of Congress (LC) subject headings. Each record had an average of 1.4 LC subject headings. However, 18.6% of the records did not have any LC subject heading assigned to them
