The challenge of networking is now being extended to cooperative library and information center systems. There are new demands for improved techniques for image storage and transmission, specifically including automated storage and retrieval of microforms and ultra-microforms and new developments in graphic and facsimile transmission. In this…

The plasma panel has potential as a computer output display device; and when perfected, may even be suitable for commercial television. In its normal operation the plasma panel exhibits a bistable range in which the cells can exist in either of two stable modes. The "on" state results from a discharge every cycle, and the "off"…

This report describes work concerned with the statistical evaluation of the output of MEDICO automatic indexing procedure. The statistical tests were designed to examine the validity of the assumptions which formed the bases of the indexing algorithms with primary emphasis on the algorithm development for the computation of weights and links. Some…

A simulation study of library-based information retrieval systems is described. Basic models for each of several important aspects are presented: (1) user behavior, emphasizing response to quality and delays in services; (2) the scheduling of services and the organization of the machine-readable files; and (3) the distribution of conventional…

A prescriptive materials laboratory, called the Educational Modulation Center, (EMC) provides teachers and consultants with immediate access to materials for use in specific teaching situations. Materials included in the EMC files are carefully analyzed according to mental age level, material format, general and specific content, stated purpose,…

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.),…

The purpose of this document is to present a final description of the original MEDLARS system as it evolved through four years of operation. The system is described as it was functioning on January 1, 1968. Among the various system elements discussed are: (1) the input subsystem, including journal selection and coverage, Medical Subject Headings…

Factors for consideration by an industrial education planning committee are discussed. Selection, purchasing, and storage of new types of equipment and supplies, in addition to students' project storage, are noted as worthy of consideration in planning the shop facility. Planning factors for the various types of industrial arts laboratories are…

The scope of a manual-automated system serving the 40 libraries and the teaching and research community of Stanford University is defined. Also defined are the library operations to be supported and the bibliographic information storage and retrieval capabilities to be provided in the system. Two major projects have been working jointly on library…

The broad objective of this investigation was to explore the potential and applicability of automatic methods for the indexing of drug-related information appearing in English natural language text and to find out what can be learned about automatic indexing in general from the experience. More specific objectives were the development,…

A description is provided of the structure, contents, and potential uses of a National Storehouse of Educational Materials Successes. The Storehouse is depicted as being a collection of evidence relating to what works in education. Details are presented on its contents, its expected users, the functions it could serve, and its operational and…

An examination of the nature of memory reveals that the representation of knowledge cannot be separated from the uses of knowledge. The answering of questions is not a simple retrieval and response of stored information; rather the process is embedded in a general structural framework containing knowledge of the questioner, the question, and the…

The computational complexity of a formal process for the construction of term classes for information retrieval is examined. While the process is proven to be difficult computationally, heuristic methods are applied. Experimental results are obtained to illustrate the maximum possible improvement in system performance of retrieval using the formal…

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…

The Retrospective Conversion (RECON) Working Task Force investigated the problems of converting retrospective catalog records to machine readable form. The major conclusions and recommendations of the Task Force cover five areas: the level of machine-readable records, conversion of other machine-readable data bases, a machine-readable National…
