Presents a system model for transmission of input data that is coming from terminals of users in a limited user resource-sharing environment. Performance of a mini/microcomputer receiving mixture of picture-phone terminal data is analyzed with constant service times, synchronous transmission, and single-server interruptions through first-order…

A generalizable procedure for the analysis and design of information systems is described in the context of allied and supporting data methods, design assessment, and project management considerations. This procedure follows from a view of information systems development as a complex series of goal-directed iterations, rather than a well-ordered…

This article defines three separate categories of microcomputers--personal, desk-top, multi-user devices--and relates storage capabilities (expandability, floppy disks) to library applications. Highlghts include de facto standards, operating systems, database management systems, applications software, circulation control systems, dumb and…

The manual describes the generalized information retrieval Query System and provides procedures and instructions for creating the data base, loading a time-sharing computer, and retrieving specified information via a remote terminal. Using the system, an analyst may load into computer storage, in a pre-defined format, information or data and then…

The first interactive (on-line) computerized use of the ERIC files by the U.S. Office of Education is reported in the form of an evaluation of the DIALOG system conducted at the ERIC Clearinghouse for Educational Media and Technology. Descriptions of the purposes of the study, of the DIALOG system (developed by Lockheed Missiles and Space Co.),…

This discussion of uploading (the transmission of information from local memory to a remote system) covers benefits, disadvantages, host system features, technical aspects, and four examples of uploading using CROSSTALK. Examples include function keys, searcher assistance with commonly-used terms, the use of hedges and boiler-plate searching, and…

Describes computer operating systems applicable to microcomputers, noting hardware components, advantages and disadvantages of each system, local area networks, distributed processing, and a fully configured system. Lists of hardware components (disk drives, solid state disk emulators, input/output and memory components, and processors) and…

This document is a preliminary statement of a proposal designed to achieve a greater cooperative sharing of library resources and services in the state. Features discussed include: (1) information about both the print and nonprint inventories of each postsecondary educational library; (2) rapid querying and acknowledgement of interlibrary loan…

A one-to-one network of communication, labeled SYSTEM-3, will come into being as a result of the demands of the public for information. In general, this form of communication system serves an asymmetric communication need--the user supplies a group of control signals that modulates the automatic flow of large amounts of information from a central…

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…

The OSIRIS system is a prototype information retrieval system having the following components: an automated microfiche file having a capacity of 5000 punch card sized microfiche with a remote control 21 inch TV console for retrieving, magnifying (0-250X), and displaying any of the images on the microfiche; and a remote computer terminal for the…

A generalizable procedure for the analysis and design of information systems is described in the context of allied and supporting data methods, design assessment, and project management considerations. This procedure follows from a view of information systems development as a complex series of goal-directed iterations, rather than a well-ordered…

Describes objectives of a museum information system: to capture photographic, lineal, and textual documents in high resolution digital images; to convert digital images of text to standard computer code; and to retrieve appropriate code automatically through keyword searching of full text. System assembly and planned and potential applications are…

The PLATO IV computer-based educational system contains its own communications hardware and software for operating plasma-panel graphics terminals. Key echoing is performed by the central processing unit: every key pressed at a terminal passes through the entire system before anything appears on the terminal's screen. Each terminal is guaranteed…

This report describes an experimental system for remote direct access to files of computer-stored information which has been indexed by the Universal Decimal Classification (UDC). The data base for the experiment consisted of references from a single issue of Nuclear Science Abstracts. The Special Subject Edition of UDC for Nuclear Science and…
