All educators need information to make good decisions. Surveys of teachers and education majors reveal that one of the best international databases available, ERIC, is overlooked as an information source. The ERIC system is described in detail, and users are encouraged to become contributors. (Author/MT)

Review of 17 databases available through BRS (Bibliographic Retrieval Services) and/or DIALOG provides addresses of database producers, beginning date of files, and descriptions, including information which may not be given in database documentation. Two new services provided by BRS and DIALOG and three vendors with wider audiences are also…

The first of a three part series, this review covers the online bibliographic and numeric databases of physics, mathematics, and computer science. Two database directories are mentioned, and a table listing databases, producers, major subjects, and starting dates is appended. Fifteen references are provided. (EJS)

This overview of 47 online sources for physics information available in the United States--including sub-field databases, transdisciplinary databases, and multidisciplinary databases-- notes content, print source, language, time coverage, and databank. Two discipline-specific databases (SPIN and PHYSICS BRIEFS) are also discussed. (EJS)

General information and specific tips for finding resources in the ERIC database highlight advantages and disadvantages of manual searches (who can perform search, location of ERIC collections, procedures for conducting search) and computer searches (results, cost, turnaround time). Procedures for obtaining access to actual copies of ERIC…

Farradane's relational indexing appeared applicable to the scientific area of the properties of metals and gave good results with a greater depth of indexing. (Author/PF)

The cataloging data bases, Ohio College Library Center (OCLC) and Blackwell North America (B/NA) are compared. While OCLC provides cataloging for a larger percentage of titles, the B/NA data base is very valuable. B/NA is less expensive to use and has comparable peripheral services. (Author/AP)

Today many data warehousing systems are data rich, but information poor. Extracting useful information from an ocean of data to support administrative, policy, and instructional decisions becomes a major challenge to both database designers and measurement specialists. This paper focuses on the development of a data processing system that…

At the international level, a lack of diffusion of Mexican art and architecture in indexes and abstracts has been detected. Reasons for this could be lack of continuity in publications, the use of the Spanish language, lack of interest in Mexican art and architecture, and sporadic financial resources. Nevertheless, even though conditions are not…

The effectiveness of four methods of handling missing data in reproducing the target sample covariance matrix and mean vector was tested using three levels of incomplete cases: 30%, 50%, and 70%. Data were selected from the National Education Longitudinal Study (NELS) database. Three levels of sample sizes (500, 1000, and 2000) were used. The…

An English summary is provided for this French article which describes the first stage of a research project using the Bose, Ghosh and Abraham theory with attributes of multiple values applied to a file containing a large number (10 6) of records. (7 references) (Author/SJ)

A study was undertaken to classify mechanically a document collection using the free-language words in titles and abstracts of physics research papers. Using a clustering algorithm, results were obtained which closely duplicated clusters obtained by previous experiments with citations. A brief comparison is made with a traditional manual…

Substantial degrees of compression of bibliographical data bases result from the application to them of a modified form of run-length coding. (14 references) (Author)
