The U.S. Army Aeromedical Research Laboratory (USAARL) is often required to make specialized measurements and perform applied research in aircraft-related areas of environmental medicine. Rapid access to the periodical literature is essential for the completion of many of these projects. A growing file of reprints from the periodical literature is…

The information retrieval demonstration and research project was designed to demonstrate the computer terminal system of information retrieval from a central computer. Specifically, the system concentrated on computer searching of the ERIC system. The demonstrations took place by locating nine terminals in volunteer districts and conducting…

A technical data file concerned with the technology of Instructional System Development suitable for a variety of users was developed. The file was prepared in a way amenable to later computerized storage and retrieval. General information sources and indexes of highly probable relevance were reviewed with key words and relevant specialty journals…

This document describes the Ohio Board of Regents' Uniform Information System which became operational during the fall term of 1966. Incoming data are received on punched cards or magnetic tape from 35 state-assisted universities and colleges, separately describing operating conditions at a total of more than 55 campuses. All incoming reports…

Human individuals, social organizations and societies are alike in that their knowledge of past events is to some extent maintained and brought to bear on their behavior. On the individual level we know quite a bit of how this is accomplished. However, on the social level we know close to nothing. It is not the task of this paper to ascertain the…

The existing volume and increasing growth rate of documented information has resulted in numerous efforts to construct operational Document Storage and Retrieval Systems, as a practical solution to the demand for information storage and retrieval. Accompanying the surge to build more and better and bigger Document Retrieval Systems (DRSs), was the…

Least cost decision rules for transferring documents from primary to secondary storage are developed from a dynamic programing model of an information system. The program is constrained to provide for a minimum acceptable level of user benefits. Knowledge of the physical size of the primary storage area and the fraction of documents returned from…

The materials of a library, exemplified by books, have traditionally been viewed as presenting two aspects involving two distinct problems: their description and control as unique items, and their treatment as sources of information on various subjects. But this view has tended to overlook a third fundamental aspect: that of the "works" which are…

This report presents an analysis of the problem of descriptive cataloging as a whole: the aspects of the problem, the questions they raise, the issues involved, the course adopted in the new "Anglo-American Cataloging Rules," and the principles that would serve best the objectives of the catalog.

This report describes an information system designed to aid individuals within the Greated Cleveland Teacher Education Centers. Three components of the system are specified: information gathering or input, a data bank, and reports. Following an overview of the teacher education centers and information system, the primary design of the information…

This report provides a complete and up-to-date review of the abstracting and indexing services available in water resources engineering. Between 1955 and 1970 the number of services in this field increased from about 20 to 40. This exponential growth or doubling every 15 years suggests that by 1985 there will be 80 abstracting services in…

The benefits of utilizing text compression for CAI are evaluated, and an analysis of core storage, decoding, and CPU time are presented for the PDP-10 system. (RAO)

Demonstrates that hierarchical naming schemes--one with a single namespace and fixed root spread over all machines in a distributed system, and a second with total namespace composed of some aggregation of individual namespaces of each component system's filestores--can coexist in distributed computer systems. Combined system's design is…

Explains steps in process of tranforming data from current form to one ready for publication on CD-ROM, i.e., disc layout, file format, building the master tape, and input to mastering facility. The conversion of a product currently existing in book form into a computer-based searchable database is described. (MBR)

Built-in data structures are the registers and memory words where binary values are stored; hard-wired algorithms are the fixed rules, embodied in electronic logic circuits, by which stored data are interpreted as instructions to be executed. Various topics related to these two basic elements of every computer program are discussed. (JN)
