This report outlines a generalized storage scheme for large files of highly structured data, or catalogs, and describes their realization on magnetic tape. Each datum, large or small, is assigned to one of a number of data classes of which a user may define any number. The over-all organization of a catalog is given by a map that imposes a tree…

Presents examples of bibliographic, full-text, and numeric databases. Also discusses how to access these databases online, aids to online retrieval, and several issues and trends (including copyright and downloading, transborder data flow, use of optical disc/videodisc technology, and changing roles in database generation and processing).

An existing experimental document and reference retrieval system operating in batch processing, tape oriented mode was converted to an on-line mode with user interaction. Objectives were faster response time, integration of functions, and system accessibility at user location. Effects on file organization, addressing techniques, file maintenance,…

This review of international information exchange formats focuses on the international standard ISO 2709 and MARC formats, "UNISIST Reference Manual," UNIMARC (Universal MARC format), the Common Communications Format, centralized network formats (International Serials Data System, MINISIS, regional), International MARC network study…

This online pilot project demonstrates the feasibility of using the OCLC transaction tapes to create an online catalog, and the utility of the BRS database structure for loading this data and for online searching. It also shows the feasibility of a user-cordial interface for patrons and for staff and provides an opportunity to test many factors…

The objectives of the MASFILE-I Pilot Project were (1) to test the utility and cost of compiling a manipulative data base from remote card files; (2) to test the utility of the Administrative Terminal System (ATS) for inputting bibliographic data into computer files from catalog card copy at a central location; (3) to test the adequacy of a…

The Science Meta-Analysis Project (SMAP) resulted in the meta-analysis of a sizable proportion of the research in pre-college science education. Seven broad questions were examined during the study. These include the effects of different curriculum programs, effects of different instructional systems used in science teaching, effects of various…
