Research in networking of heterogeneous interactive bibliographic retrieval systems is being conducted which centers on the concept of a virtual retrieval system. Such a virtual system would be created through a translating computer interface that would provide access to the different retrieval systems and data bases in a uniform and convenient…

Organization of communication between the center of an automated system of information exchange and the subscribers to the system is described. The three requirements are: (1) those technical communication means must be chosen which will provide effective and convenient avenues for calls from the subscribers to the center, (2) the required…

Three projects, each covering certain selected aspects of a potential information storage and retrieval system, were part of a study by the Ontario Educational Communications Authority (OECA) to explore various means for extending the usefulness of audiovisual materials. Project Dataset began the collection, classification, and cataloging of…

In terms of examples drawn from clinical and research data files, one of the objectives of this study is to illustrate several factors that have combined to delay the implementation of medical data bases. A primary factor has been inherent in the design of computer software. The languages currently on the market are procedural in nature: they…

This report discusses the development and implementation of computer-related teaching materials for undergraduate physics courses. A list of the computer dialogs developed, with a short description of each, is included. The types of dialog are: (1) development of an interactive proof, (2) assistance in problem solving, (3) diagnosing and filling…

Experience of browsing with a text retrieval system is reported. The technique discussed consists of adding and deleting query terms on successive interactive cycles. The number of hits consistently increased, while the number of false drops consistently decreased on successive cycles. The search system used allows non-Boolean free form query…

The Indiana Seminar on Information Networks (ISIN) was the result of the realization that many Indiana librarians were not fully aware of the benefits of library networking and were not really using the Indiana TWX network to its fullest advantage. In addition, it was felt that the statewide TWX arrangement and its available services needed more…

This document describes and compares on-line library circulation systems that have been reported as operational or developing, based on a non-comprehensive survey of published articles and public and restricted technical documentation. A checklist of components and features is used to tabulate if and how each system accommodates four selected…

Contained in this report are the results of the second phase (July, 1968 - June, 1970) of the File Organization Project, directed toward the development of a facility in which the many issues relating to the organization and search of bibliographic records in on-line computer environments could be studied. The papers in this volume deal…

Communications technology that is or will soon be available can help create better opportunities for mass discussions about public issues. The hardware and software prerequisites for such discussions are: capacity to address participants, facilities for real-time dialogue between geographically dispersed groups, continuous feedback between…

The purpose of the investigation was to determine how effectively biomedical practitioners, with a minimum of introduction to the system, can conduct on-line searches to satisfy their own information needs. The searches were conducted on the Abridged Index Medicus data base as implemented on the on-line ELHILL system (AIM-TWX). ELHILL is the ORBIT…

This workbook is designed primarily for graduate library school students in a supervised laboratory setting as an adjunct to a formal course on computer based reference services. The DIALOG system has the capability to search several large on line files, and the workbook is designed to be used in conjunction with the Lockheed DIALOG Manual. Eight…

Research programs of the University of California (UC) Institute of Library Research (ILR) for the period July 1975 to June 1976 included: (1) error analysis of the UC Union Catalog Supplement (UCUCS), (2) error analysis of on-line bibliographic data bases, (3) planning data for UCUCS-2 conversion planning, and (4) document delivery support for…

Discusses the contemporary antagonism between the information seeker and the highly technological information storage systems. Arguments are concerned with the price, availability, and response time of various retrieval methods, ranging from the card catalog to the computer, in addition to the user's problems with the more complex systems.

Presents a bibliometric study of on-line information retrieval literature, including examination of the literature's growth rate, the dispersion of journal literature, sources of literature, and author citations and contributions. An unsuccessful attempt was made to apply Bradford's Law to the literature. (CWM)
