A defense-wide study in cooperation with GSA to: evaluate the availability and applicability of advanced microform and equipment to the Federal Catalog System (FCS) and Defense Integrated Data System (DIDS) publications requirements; recommend a type of microform and compatible reader for standardization throughout the DOD; and develop a…

The University of Iowa Computer Center obtained the ERIC data base on March 15, 1971. In the early stages, the files were reduced in size by eliminating some of the fields, and the program was modified to allow a maximum of 100 hits per search request. This manual is intended to aid the new users during the system's first year of operation. It…

A model of a generalized information storage and retrieval system is proposed. The model consists of six subsystems (or blocks): logical processor, selector, descriptor, file, locator, document file, and analysis block. These subsystems function in a partial environment defined by the user and data blocks. Proceeding from a verbal description, a…

A retrieval system is considered in which document descriptions are stored and accessed in groups called clusters. All items in a cluster meet common similarity criteria and are represented by a composite entity called a profile. In large collections, profiles themselves are clustered and additional levels of profiles are generated. This entire…

The hypothesis that the mechanistically identifiable citation link characteristic (i.e., mention of a given reference more than once within the same research paper) indicates a close and useful relationship between a citing and a given cited paper is tested and accepted. (Author)

Presents the "Evidence-of-Existence" information system in which the structure is developed, with application of cybernetic concepts, as an isomorphic model in analogy to the system structure of communication technology. Three criteria of structuring are postulated: (1) source-channel-sink, with input-output characteristics, (2) filter-type…

Viewdata, an interactive service that may revolutionize the public's access to information, transforms the home television receiver into a home information retrieval terminal via a telephone, which connects it to a central computer covering a wide range of data bases. Its origins, costs, and implications are discussed. (Author/MBR)

Women respondents, aged 66 to 76, provided exact answers to an average of 90 percent of the questions they were asked. Reliability ratios, which were calculated for the many variables, including use of contraceptive methods, were comparable with those observed in previous studies of women in the childbearing years. (Author)

The application of computers to retrieval of primary documents is illustrated by descriptions of the Baltimore Region Institutional Studies Center (BRISC), which operates an automated system for retrieving records by subject, geographic location, and date; and ARCHON (ARCHives ONline), the online program developed to meet BRISC retrieval…

The prototype AID system for search strategy formulation currently operational on TOXLINE is described. Utilizing a compressed in-core hash table, it relies on statistical frequency distribution information about term occurrence in a set of document texts retrieved in response to a Boolean search query, and the occurrence frequencies of the same…

Describes a course which provides students with hands-on experience at a computer terminal, and includes segments on how to conduct a reference interview using counseling techniques, how to evaluate and select information retrieval services and equipment, and discusses the impact of computerized information retrieval on libraries. (JAB)

Outlines the concepts and facilities of SLC-II, a basic support for R&D in automatic documentation and language translation, and gives a detailed description of its use in automatic indexing. The design and running of a full-scale pilot project is described, with a parallel experiment in the effectiveness of "thesaurus enrichment" by semiautomatic…

Separation of catalogs by script, and, within non-Roman scripts, by language, is discussed as an alternative to Romanization. Difficulties are considered and a solution is suggested--the establishment of separate machine readable data bases for each script and a National Union Catalog in microform for the separate "registers." (Author/MBR)

The paper describes a computerized system designed to provide a quick and economical method of in-depth access to individual publications. It is currently operating in a network configuration in Ontario and Quebec, and independently in other Canadian and United States libraries. (Author/JAB)

Explains the organization of a cross index file system for the storage and retrieval of teaching materials. (CP)
