Analyzes computer terminal memory performance in terms of overflow probability and average queueing delay, and presents new method to derive a closed expression for data arrivals with Erlangly distributed interarrival times and an approach to derive steady state probability expressions of the terminal memory content process. Twenty references are…

Analyzes structure of, and data in, the OCLC-MARC record in the form delivered via OCLC's Tape Subscription Service, and outlines important processing functions involved: "unreadable tapes," duplicate records and deduping, match processing, choice processing, locations processing, "automatic" and "input" stamps,…

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…

This thesis describes the requirements for a buffer storage device, with respect to other system components and its own limitations, which is designed to aid in the economic transmission of processed data from a central computer to distant terminals. Proceeding from the fact that tariff rates on wide band educational television channels are…

This document explains recent developments in computer science and information systems of interest to the educational manager. A brief history of computers is included, together with an examination of modern computers' capabilities. Various features of card, tape, and disk information storage systems are presented. The importance of time-sharing…

Using an IBM System/360 Model 50 computer, the New York Statewide Film Library Network schedules film use, reports on materials handling and statistics, and provides for interlibrary loan of films. Communications between the film libraries and the computer are maintained by Teletype model 33 ASR Teletypewriter terminals operating on TWX…

The state of the art for document access is briefly reviewed and a reasonably far look into the future is presented in this paper. (40 references) (Author/NH)

Heavy emphasis was placed on experiments, and interpretation of experimental results. A set of experiments was designed to yield quantitative information on how the experimental subjects used the full-text-access system, why they used it and how effective it was. A detailed report of work on this topic to date is presented. The in-depth analysis…

The papers in this volume constitute the proceedings of a symposium which examined the history, state-of-the-art and future utility of computer-based information systems. Emphasis is placed on the economics and potential uses of on-line interactive systems and their accompanying computer networks. Conceptual and descriptive papers dealing with the…

This paper describes several pilot systems of data management using telecommunications links, which have been tested by the Navy during an 8-year period in which emphasis has been on the development of relational database management systems, exchange protocols, and man-machine interface. An introduction discusses the background of the project,…

The results of a one year study to identify potential technology-based improvements in the operation, access, and utilization of the Educational Resources Information Center (ERIC) are described. Both current problem areas and future possibilities are considered with respect to the dichotomy: system components and the total system. Emphasis is on…

This paper discusses several of the trends in information handling for text-based storage and retrieval systems that are prevalent in the United States. The paper considers, in particular, specialized information products, cooperative and networking activities, and work on standards. Information products include current awareness abstract…

Microcomputers can vastly improve the efficiency of data management, data analysis, and communications in the school office, but implementation should be carefully planned, with attention to relative cost for benefits obtained, appropriateness of software and hardware, and potential security risks.

This collection of 22 papers from the Conference on Information in the Language Sciences held in Warrenton, Va., in 1966, sponsored by the Center for Applied Linguistics, stresses three themes: general trends, information needs of the languages sciences, and system design. Discussions attempt to formulate modern rational approaches to the complex…

Libraries should resist the temptation to relinquish to computing centers the burden of looking after the university's digital data record resources for a growing volume of intellectually important material will arrive at the university on digital data tapes. If the user must arrange for access to this material outside the library, he will be…
