This report examines a series of general models that represent the process of merging records from separate files when it becomes essential to inhibit identifiability of records in at least one of the files. Models are illustrated symbolically by flow diagrams, and examples of each variation are taken from the social sciences. These variations…

The development of a new scheme for classifying the more than 7,000 documents on reading in the ERIC/CRIER data collection is described. An original scheme, developed in the early days of the clearinghouse, provided a means for listing documents in any of 45 broad subject categories in the field of reading and for identification by grade level.…

The objectives of this study were to submit all the information necessary for making a decision on the establishment of a comprehensive materials data bank for West Germany. The problems investigated were: determination of the present state of the art, examination of a number of systems and other resources existing in the subject, site visits to…

Categorizes software packages for microcomputer database creation by their typical features and strengths, and discusses appropriate applications of each category. A directory of vendors for each type of software--text retrieval, file managers, database management, information storage and retrieval, integrated bibliographic systems, and library…

Reviews new educational materials designed for microcomputer use: compact disk encyclopedia derived from "Grolier's Academic American Encyclopedia"; "PC Word Power," vocabulary enhancement game; "Public Domain Software on File," 250 programs for Apple II microcomputer users; "RightWriter," program designed to teach effective writing; "Kansas…

Suggests new method of external distribution called tree partitioning that involves use of binary tree to split incoming file into successively smaller partitions for internal sorting. Number of disc accesses during a tree-partitioning sort were calculated in simulation using files extracted from British National Bibliography catalog files. (19…

Review of office filing facility filing and retrieval mechanisms for unstructured and mixed media information focuses on free text methods. Also discussed are the state of the art in handling voice and image data, problems with searching text surrogates to implement free text content retrieval, and work of Project Minstrel. (Author/MBR)

This digest provides information and advice for accessing information from the Educational Resources Information Center (ERIC) database, a federally funded information network designed to provide users with ready access to education literature. It describes the database, the best ways to access ERIC, the thesaurus of ERIC descriptors, and the use…

The evolution of Petroleum Abstracts,'' which was started in 1961, is described. The various methods used for retrieving are discussed. (5 references) (SM)

Discusses the need to analyze and develop concepts of effective data handling when new systems projects are in their initial stages of development. For one such project -- TIES -- the author examines several of these concepts within the framework of the technical capability available and the need of the user. The developmental processes and the…

Brief discussion of state-of-the-art of modeling complex information systems distinguishes between macrolevel and microlevel modeling of such systems. Network layout and hierarchical system models, simulation, information acquisition and dissemination, databases and information storage, and operating systems are described and assessed. Thirty-four…

Describes a videodisc-based information display system in which a computer terminal is used to search the online PATSEARCH database from a remote host with local microcomputer control to select and display drawings from the retrieved records. System features and system components are discussed and criteria for system evaluation are presented.…

Describes the Student Scheduling and Tracking System (SSTS), which is a computerized student record database used in Davidson High School in Mobile, Alabama. The microcomputer-based system is used in report card preparation, student scheduling, and maintaining current student records. (JJD)

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…

Discusses the national program for preservation microfilming in research libraries and suggests that microfilm is not the appropriate medium to be used. Recommendations for the electronic storage of materials on computerized databases are made; disadvantages of microfilm are described; interlibrary loan problems are discussed; and effects on…
