Described is the file organization and design of an on-line catalog suitable for automation of one million books. A method of virtual hash addressing allows rapid search of the indexes to the catalog file. Storage of textual material in a compressed form allows considerable reduction in storage costs.

The File Organization Project has made available a set of programs which are designed to operate on large files of machine readable bibliographic records. These programs are designed as an instrument for understanding and refining the techniques of bibliographic search. This document discusses four aspects of the system: (1) The retrieval program,…

Provides a generalized overview of the problems that software buyers are likely to encounter and could overcome. Experiences of Online, Inc., in purchasing programs, using software documentation or manuals, and problems with software, provide examples. (EJS)

This paper describes the IBM 1500 Instructional System which is used for computer assisted instruction (CAI), research, and demonstration at the University of Alberta. The system automatically stores a performance record of each student's responses to instructional programs, and a number of CAI support programs are accessible to perform various…

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…

Two computer programs (one batch, one interactive) are designed to provide statistics for a weighted linear combination of several component variables. Both programs provide mean, variance, standard deviation, and a validity coefficient. (Author/JKS)

Discusses the multilevel information system (MLIS), a retrieval system that integrates functions typical for database management systems and retrieval-oriented systems and provides several levels of data accessing, each developed for a different class of users. Twenty-two sources are cited. (FM)

The model circulation system outlined is an on-line real time system in which the circulation file is created from the shelf list and the terminal inquiry system includes the capability to query and browse through the bibliographic system and the circulation subsystem together to determine the availability for circulation of specific documents, or…

In addition to reviewing the characteristics of document processing systems, this paper pays considerable attention to the description of a system via a feature list approach. The purpose of this report is to present features of the systems in parallel fashion to facilitate comparison so that a potential user may have a basis for evaluation in…

Describes the development by Gould, Inc., S.E.L. Computer Systems Division, of an Information Management Package (IMP-32) for use in administration of the company's technical information center. Designing the system, the programs which are components of the system, and system functions are discussed. Included are eight figures illustrating system…

Clemson University has developed techniques and procedures to assist in the construction and maintenance of administrative systems. Procedures as well as the tools and techniques used by all systems are discussed: online report request software, online user table maintenance software, report supervisor and report writer software, etc. (Author/MLW)

The first group of papers starts with a tutorial paper which surveys the methods used in data acquisition systems. Other papers in this group describe: (1) some problems involved in the computer acquisition of high-speed randomly-occurring data and the protection of this data from accidental corruption, (2) an input/output bus to allow an IBM…

The work of the Committee on the use of automation in Swedish research libraries has differed from that of a normal study group by virtue of its heavy concentration on the practical aspects of library catalog work, the present status of which is the main theme of this report. The model presented implies total and simultaneous integration of all…

The results of the second 18 months (December 15, 1968 - June 30, 1970) of effort toward developing an Information Processing Laboratory for research and education in library science is reported in six volumes. This volume contains two parts. Part I includes: a user's guide - a guide to writing programs to TMS (Terminal Moniter System) for…

Defining a numeric database as a computer-readable collection of data predominantly numeric in nature, this article reviews techniques and technologies having a positive influence on the growth of numeric databases, such as videotex, mini- and microcomputers, artificial intelligence, improved software, telecommunications, and office automation.…
