Describes how Danbury, Connecticut justified its computer costs by consolidating school and city accounting functions. (JF)

The Canadian Department of Education developed this manual to provide teachers and administrators with information about the potential use of computers. Part I describes at length the five components of the computer input, output, storage, control, and arithmetic/logic functions) and gives a discussion of computer languages, programing, batch…

HELP--a question-answering system--enables a user, sitting at the console of a time-shared computer, to obtain information on questions typed in. This information might concern the operating system itself, the format of commands to the user interface executive program, the use of a selected subsystem, or an area totally separate from the computer.…

The paper descibes a compact and highly efficient disk file management system responsible for the management and allocation of space on moving head disk drives in a medium-scale time-sharing system. The disk file management system is a major component of the Experimental Time-Sharing System (ETSS) developed at the Learning Research and Development…

Improvements in the technology associated with the information sciences will have their primary potential impact on the distribution of costs, information flow level, information availability, and use among information channels. This improvement implied not only a capability to perform a given function, but a lower cost. For example, the trend…

The subject of access control mechanisms in computer systems is concerned with effective means to protect the anonymity of private information on the one hand, and to regulate the access to shareable information on the other hand. Effective means for access control may be considered on three levels: memory, process and logical. This report is a…

The papers and discussions of the 1975 Pacific Region meeting of the Association for Computing Machinery are presented. Topics included (1) the current and emerging state of the art in data management software and hardware, (2) relational systems with particular attention to new developments in systems for relational data bases, (3) advances in…

THE MANUAL DESCRIBES AND DOCUMENTS THE RETRIEVAL SYSTEM IN TERMS OF ITS TAPE AND DISK FILE PROGRAMS AND ITS SEARCH PROGRAMS AS USED BY THE LEHIGH CENTER FOR THE INFORMATION SCIENCES FOR SELECTED CURRENT LITERATURE OF THE INFORMATION SCIENCES, ABOUT 2500 DOCUMENT REFERENCES. THE SYSTEM IS PRESENTLY ON-LINE VIA TELETYPE AND CONVERSION IS IN PROCESS…

Although the indispensibility of access control mechanisms in data secure systems has been recognized, there is a need for more subtle protection and refined control mechanisms. This report describes context protection mechanisms which enable the same data unit to be protected differently in different contexts, the differences being determined by…

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…

Until recently, the emphasis in information storage and retrieval systems has been towards batch-processing of large files. In contrast, SHOEBOX is designed for the unformatted, personal file collection of the computer-naive individual. Operating through display terminals in a time-sharing, interactive environment on the IBM 360, the user can…

This publication provides members of the House of Representatives information about the range of on-line computer services and data bases available for their use. Section 1 is an introduction. Section 2 describes the nature and general functions of time-sharing services, information systems, and data bases discussed in the document. Section 3…

SPIRES (Stanford Public Information Retrieval System) is a computerized information storage and retrieval system intended for use by students and faculty members who have little knowledge of computers but who need rapid and sophisticated retrieval and analysis. The functions and capabilities of the system from the user's point of view are…

The report describes the Classroom Information and Computing Service (CLICS), a pedagogical computer-based information system that is used as a case study in the subject "Information Systems" in the Dept. of Electrical Engineering at M.I.T. CLICS is an abstraction of the Multiplexed Information and Computing Service (MULTICS) that is being…

A multi-language, time-sharing system (MTS-12) has been developed for the PDP-12, a Digital Equipment Corporation laboratory computer. This low-cost, core-resident system features program storage on LINC tape (3/4" magnetic tape on a 4" reel), access to the high-level interpreted FOCAL language, and a special variable storage in the user…
