Describes a simple computer-based information retrieval system which manipulates non-numeric information using a program that simulates a three-level information storage system. The system is used to create, modify, and selectively search a data base both interactively and noninteractively. (MLH)

Introduction: The conceptual framework of librarianship and information science has developed rapidly over the past decade with the prospect of application in other fields. However, transfer of concepts across branches within the field remains problematic and severely limits ability to address important information problems. Requirements: A…

This discussion of the laser videodisk begins by noting that it is an extremely high density visual storage medium that can supply instructors with vast visual warehouses to supplement instruction, whether through conventional group presentations or via individualized computer assisted instruction. Major features of the medium are then described…

Computers have changed the way information resources are handled. Large amounts of information are stored in one central place and can be accessed from remote locations. Users have a personal responsibility for the security of the system and the data stored in it. This document outlines the user's responsibilities and provides security and control…

There are four problems in modern composition bibliography that result directly from the continuing research paradigm instability in the field. The first problem is that of definition. Composition is a hybrid, practical sort of field, with very ill-defined and shifting boundaries. The recent extension of composition from "formal writing…

The Educational Resources Information Center (ERIC) offers Health, Physical Education, Recreation and Dance (HPRD) faculty and students access to the largest collection of educational literature available today. This digest discusses how to assess ERIC, the importance of the Thesaurus of ERIC Descriptors, and how to use Thesaurus descriptors, and…

This manual on microcomputer-based database management programs provides a description of the key characteristics of database software as well as guidelines for designing a database, uses of database programs, and selecting the right software. Three sets of concepts related to database management are listed and explained: creating a database,…

This document defines and describes electronic databases and provides guidance for organizing a useful database and for selecting hardware and software. Alternatives such as using larger machines are discussed, as are the computer skills necessary to use an electronic database and the use of the computer in the classroom. Files, records, and…

Two articles provide: (1) instructions for gaining telecommunications access to CHILDES, a child language database; and (2) the conventions guiding transcript coding in the database. The first article provides access instructions for telecommunications systems, the commands a user would need to know, and brief notes on searching and other aspects…

Designed to minimize information overload in telecommunications systems, the formal model developed in this paper predicts the usefulness of a message based on the available message features, and may be used to rank messages by expected importance or economic worth. The assumptions of binary and two Poisson independent probabilistic distributions…

Many individuals are concerned that the "knowledge explosion" in special education is making it difficult to keep up with research in the field. However, at the same time that knowledge has been expanding, efficient ways of locating knowledge have developed and additional sources of integrative reviews of research have appeared. The paper…

All evidence from all sources--the literature, survey of practitioners and educators, selected educational programs, and the views of abstractors of data for computerized information retrieval--points to the body of public relations knowledge as consisting of all knowledge as it applies to resolving public relations problems and goals. What…

This discussion of the development of database management systems specifically created to support qualitative research identifies two main problems in qualitative approaches, i.e., the issues of data collection and analysis, and the cumbersome nature of traditional qualitative approaches. These problems are reviewed with a comparison of the…

This workbook is the second in a series of three that has been integrated into the chemistry curriculum for majors at the University of Vermont. The workbook, which consists of exercises designed to provide undergraduate students with foundation skills in the use of professional literature, is introduced late in a second semester organic chemistry…

This document is the newest revision of the third manual documenting the National Agricultural Library database. Since it began in 1970, the AGRICOLA database has continued to grow and to change steadily; new subfiles have been added, database record formats have been expanded, and subject category code schemes have been modified several times.…
