After discussing the nature of timeliness and its importance to the user of information systems, this document examines the factors which affect timeliness in three subsystems of the scientific communication system. The first subsystem moves a document from the existence of new knowledge to the point of entry into an information system; the second…

This paper presents a comprehensive framework for the evaluation of online bibliographic retrieval services and provides an example of its use with the Educational Information System for Ontario (EISO). A systems approach, incorporating traditional categories of input, output, process, and feedback, is used to develop the model; in its…

This discussion of the design, development, and operation of information systems functioning at the national or international level focuses on some of the current interests and concerns of those networks designed to facilitate the sharing or exchange of particular types of nonprint media (NPM) materials. Three categories of NPM materials/resources…

For the past seven years, the Division of Educational Research Services at the University of Alberta has been operating an IBM 1500 CAI system. This paper describes demonstration projects set up in anticipation of the establishment of remote CAI in the North West Territories. These include a moon landing simulation program; a diagnostic program in…

With emphasis on currently operating and planned systems that assist users in accessing available network services, this report identifies the techniques used in network access devices. By examining these devices, the trend toward improving the interface between the user and the computer is brought more clearly into focus and up to date. One…

An experimental program placed computer terminals in four San Francisco Bay Area public libraries to be used to provide on-line computer search services to library patrons. The first few months of operation of the experiment showed that there was a significant impact on the participating libraries, on the library patrons, and on the community and…

The Migrant Student Record Transfer System (MSRTS) was designed to permit schools to share the accumulated understanding of many prior schools about the migrant child and his needs. This shared migrant student information frees a school to focus its energy on serving a child's needs instead of using it to identify those needs. If the MSRTS is to…

A computer program for the simulation of complex continuous process in real-time in an interactive mode is described. The program is user oriented, flexible, and provides both numerical and graphic output. The program has been used in classroom teaching and computer aided design. Typical input and output are illustrated for a sample problem to…

Described are existing components that could be linked together to form a Western Bibliographic Network or could provide products and services for Network members. The components reviewed are: (1) state library agencies, research libraries, state and multistate library networks, and other regional organizations in the 17-state western region and…

In March 1974, a study was undertaken at Northwestern University to examine the role of the library in providing information services based on computerized data bases. After taking an inventory of existing data bases at Northwestern and in the greater Chicago area, a committee suggested ways to continue and expand the scope of information…

The workshop had its genesis in the belief that interactive bibliographic data base searching will become an essential function of reference service and that there is a need for indepth training and more communication with suppliers--the on-line system supplier and the data base supplier. The workshop included presentations by data base suppliers,…

People use a variety of plausible, but uncertain inferences to answer questions about which their knowledge is incomplete. Such inferential thinking and reasoning is being incorporated into the SCHOLAR computer-assisted instruction (CAI) system. Socratic tutorial techniques in CAI systems such as SCHOLAR are described, and examples of their…

The report describes Wisconsin's information retrieval system with remote, on-line computer access to nearly 200,000 educational documents. Briefly outlined are the operations and indexing of materials for the computer program, documents of the Educational Resources Information Center (ERIC), file access, training sessions, and remote location…

Librarians discuss the library use of computers without concerning themselves with the technical aspects of computer software or hardware at this Library Automation Research and Consulting (LARC) Association institute. The first paper, "State of the Art Review," examines some of the fundamental problems of automated serials control, and…

A low cost method for delivery of computer services to homes and schools through interactive television called time-shared, interactive, computer controlled, information television (TICCIT) has technical qualities such that it is individualized, computerized, multimedia, and provides unlimited points of entry and delivery of information. TICCIT's…
