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…

Discusses database design concept termed "normalization" (process replacing associations between data with associations in two-dimensional tabular form) which results in formation of relational databases (they are to computers what dictionaries are to spoken languages). Applications of the database in serials control and complex systems…

Defines and discusses bibliometrics, particularly as carried out in automated systems. The specific requirements to which data should conform to support bibliometric analysis are detailed and explained, and the Intelligent Gateway of the Lawrence Livermore National Laboratory is described.

Provides statistical summaries of database development and growth for 1979, based on the "Database of Databases" file at the University of Illinois Information Retrieval Research Laboratory. Bibliographic, bibliographic-related, and natural language databases are analyzed in four subject categories: scientific/technical, humanities,…

This preliminary study attempted to determine the most effective search strategies for the topic "health effects" in relation to specific chemicals and/or pollutants--in this case, asbestos--for each of five selected Lockheed DIALOG data bases: BIOSIS Previews, Chemical Abstracts Condensates (Chemcon), NTIS, Enviroline, and Pollution…

Discusses methods for designing search strategies for maximum recall, including minimizing the number of concepts intersected, isolating key subtopics, adapting the strategy to the database, and minimizing problems with search words and codes. (Author/RAA)

This data tape--NCES.HEGIS.TAXONOMY.FILE1981--represents a crosswalk between the old taxonomy of the Higher Education General Information Survey (HEGIS) and the newer taxonomy of the Classification of Instructional Programs (CIP). The 838 records give the old taxonomy and 4-digit codes and the new taxonomy and 6-digit codes for the conventional…

Estimates of frequency of spelling errors are made based on a sample of 3,600 index terms drawn from 11 bibliographic data bases. The impact of these errors is discussed by tape supplier, tape user, and end user; with some suggestions for search strategies.

Reports results of survey of United States online database producers designed to determine number of personnel employed in intellectual production of databases and provide basis for generation of people employed in frequently recurring staff categories. Implications for education based on needs suggested by staffing patterns are examined.…

Reports on a quantitative categorical analysis of metadata elements in the Dublin Core, VRA (Visual Resource Association) Core, REACH (Record Export for Art and Cultural Heritage), and EAD (Encoded Archival Description) metadata schemas, all of which can be used for organizing and describing images. Introduces a new schema comparison methodology…

Presents analysis of online search patterns within user searching sessions of National Library of Medicine ELHILL system and examines user search patterns on the CATLINE database. Data previously analyzed on MEDLINE database for same period is used to compare the performance parameters of different databases within the same information system.…

This introduction to online numeric database systems describes the types of databases associated with such systems, shows the major functions which they can perform (retrieval, analysis, display), and identifies the major characteristics of user interfaces. Examples of numeric database use are appended. (EJS)

Briefly looks at the present use of computers in library reference service for bibliographic database searching, then surveys the future as indicated by recent developments and ongoing research. Cooperative online reference, local databases, and increasing ease of online information retrieval are discussed. Included are 40 references. (Author/JL)

Describes the Context Information System, a prototype retrieval system designed for online searching in an educational environment. Use of the system in Israeli high schools to encourage the development of research skills is discussed, emphasizing the use of databases for hypothesis testing and comparative analysis of data.

Imagine being able to engage students in learning statistics. Teachers would need their students to have access to a large database of real data, preferably about students. It would be even better if students were part of the database. Ideally, the data would enable students to ask questions of interest to them. For a teacher, it would be…
