REQUIREMENTS OF A PILOT INFORMATION SERVICE FOR EDUCATIONAL RESEARCH WERE INVESTIGATED BY ISOLATING THE CHARACTERISTICS OF DOCUMENTS JUDGED RELEVANT BY QUESTIONERS (USERS). IN ADDITION, RETRIEVAL STRATEGIES WERE COMPARED ON THE BASIS OF THE RELEVANCE AND RECALL FACTORS FOR EACH STRATEGY. THE FOLLOWING CONCLUSIONS WERE REACHED--(1) IN PROGRAMING…

THIS PRELIMINARY STUDY FOR DEVELOPING A SYSTEM OF INDEXING MATERIAL ON INSTRUCTIONAL TECHNOLOGY INCLUDED--(1) A SURVEY AND REVIEW OF THE LITERATURE ON INFORMATION STORAGE AND RETRIEVAL, (2) AN EXAMINATION OF LOW-COST INFORMATION STORAGE AND RETRIEVAL SYSTEMS, (3) VISITS TO A NUMBER OF ORGANIZATIONS AND AGENCIES USING EITHER MANUAL OR MECHANIZED…

This fifth and final report describes activities since June, 1965. Centralization of the Eisenhower Library Collection was completed early in 1965 and a circulation system became operational in April, 1965. The main portion of this report focuses on various aspects of the circulation system such as preparation of identification cards; the…

A model for developing a data control system in an integrated management information system. (RA)

Discusses data model role in an office filing facility, office data model requirements, and various modelling paradigms for office data modelling. Data model application to a typical collection of office data is presented, filing and retrieval operations are illustrated, and proposed research into other office data modelling aspects is outlined.…

Examines the structure and components of information storage and retrieval systems and information filtering systems. Identifies 13 components as representations of data objects (copies, excerpts, descriptions, abstractions, and identifying references) and functions that operate on them. Reduces the functional components to transformation and…

Outlines the important factors to be considered in selecting a database management system for use with a microcomputer and presents a series of guidelines for developing a database. General procedures, report generation, data manipulation, information storage, word processing, data entry, database indexes, and relational databases are among the…

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…

A RETRIEVAL MODEL WAS DEVELOPED FOR TEACHING AND RESEARCH PURPOSES ON THE BASIS OF VARIED WORK EXPERIENCE AND ANALYSIS OF TECHNICAL DOCUMENT RETRIEVAL AND LIBRARY SERVICES. THE MODEL IS BASED ON SHANNON'S COMMUNICATION MODEL BUT IDENTIFIES THE WOULD BE READER, OR DESTINATION OF RECORDED MESSAGES, AS THE ACTIVATOR OF RETRIEVAL SERVICES. TWO MAIN…

Part I presents an initial review of the literature pertinent to the research problem. The literature review has two divisions. In the first division, the previous works relating to systems analysis studies of libraries or information storage and retrieval systems are reviewed. The second division includes the review of literature pertinent to the…

The paper reviews the research on design and operation of research libraries sponsored by the Purdue University Libraries and the Purdue School of Industrial Engineering. The use of mathematical models in library operations research is discussed. Among the mathematical methods discussed are marginal analysis or cost minimization, computer…

An outline is presented for a digital computer simulation model for an information network for the State of California. The methodology of simulation is discussed initially. The problems presented by the very large size of the system, in terms of materials, users, communication connections are depicted, and solutions are suggested which permit…

Analyzes computer terminal memory performance in terms of overflow probability and average queueing delay, and presents new method to derive a closed expression for data arrivals with Erlangly distributed interarrival times and an approach to derive steady state probability expressions of the terminal memory content process. Twenty references are…
