A description of a retrospective document retrieval system is given in which equifrequent fragments are used as language elements for compression coding and retrieval. The critical parameters governing the system are identified, and restrictions imposed by the parameters on the selection of fragments are outlined. Changes necessary in the…

Because the cost of computers has decreased significantly in the last few years and their capabilities have increased significantly, a minicomputer is proposed as the front end processor for an automated library system of a medium sized library. The local library processor is to be connected to a larger computer which hosts the data base and…

This volume consists of an index of questions repeated in public opinion surveys, and the variants of these questions. The questions included are drawn from American national samples (primarily of the general population) conducted by AIPO (Gallup) NORC, and Roper, and archived at the Roper Public Opinion Research Center. The basic data for over 90…

Response time in large, inverted file document retrieval systems is determined by time required to access files of document identifiers on disk and process a Boolean search request. A specialized computer system has been devised that can perform a complicated sample search involving 70 terms and over 60,000 document references 12 to 60 times…

Instructional Management System (IMS) information cycles from participating schools to the Southwest Regional Laboratory (SWRL) for processing, returning again to the school in the form of summarized reports of pupil data. One segment of this cycle is managed by the IMS pupil data base processing program. The program generates reports from…

The Library Education Experimental Project (LEEP) involved the establishment of a computer-based laboratory for library science students, utilizing the Library of Congress MARC (Machine-Readable Cataloging) magnetic tapes. Assignments in several classes (reference and bibliography, cataloging, and technical services) involved the use of these…

STITE (Scientific and Technical Information Transfer for Education) is a proposed system for the transfer of information from the many computerized information banks to the field of science education. A description of STITE with its auxiliary systems first outlines the goals and objectives of the research. Next, selected science and technology…

This research was conducted in a rural community college and examines two methods for extending community services and the response of the community to the establishment of a Community Resource Center. The basic questions asked in this study are threefold: (1) What strategies can be effectively used by a rural community college in extending its…

An educational methodology for the development of interdisciplinary, problem-solving skills was developed. Called the problem laboratory, the approach focuses on linking the student with the real problems of real organizations through specifically designed data bases. Students are presented with a brief problem statement and proceed to solve the…

This collection of ten conference reports begins with "Historical Impact of Computers on the Operation of Libraries and Information Systems: A Personal Perspective" and is followed by "Tips on Computer Software: Advantages and Methods of Program Dissemination" and "BLOCS--A Unique Multi-Dimensional Approach to On-Line Circulation". Next, libraries…

A newly developed instructional system for introductory college geography links the computer with the geographer's most traditional and essential tool--the thematic map. The use of the computer overcomes the logistical and mechanical problems associated with the teaching of thematic mapping to large groups and helps the students to focus upon the…

A bulk data input processor which is available for the Rapidly Extensible Language (REL) English versions is described. In REL English versions, statements that declare names of data items and their interrelationships normally are lines from a terminal or cards in a batch input stream. These statements provide a convenient means of declaring some…

The purpose of this guide is to give an up-to-date presentation of the information service offered by the documentation center at the Royal Institute of Technology (RIT) and to facilitate the utilization of the service. The guide gives a general account of the multidisciplinary computerized current awareness service (SDI) and a detailed…

Efforts of this planning study are limited to the pressing needs of state agencies for planning which were identified earlier, plus an attempt to identify data elements common to many agencies that relate directly to the State Economic Development Planning Program. The major categories of data types essential to the planning system are land use,…

A more complete definition of the features offered in present day generalized data base management systems is provided by this second technical report of the CODASYL Systems Committee. In a tutorial format, each feature description is followed by either narrative information covering ten systems or by a table for all systems. The ten systems…
