This handbook examines sources of information useful to educators and educational consultants who wish to learn about innovative practices and/or solutions to educational problems in other schools. A discussion of information storage describes the access to information in reports, periodicals, unpublished reports, and other materials through such…

This collection of search formulations was assembled to assist in Dialog Searching of the ERIC data base. The formulations represent modular building blocks or concepts that occur frequently when searching this file. They have been formulated and described in such a way that they can be used as given, or they can be modified to suit specific…

A committee on rules fur cataloging machine readable data files (MRDF) recommends areas for revision of the Anglo American Cataloging Rules to integrate collections of MRDF into the mainstream of bibliographic control. The 12 working papers which support and detail these recommendations are appended to this report. They include rationales for…

General Information Storage, Retrieval, and Application System (GENIRAS) is a computer-aided information system designed for the storage, retrieval, and manipulation of data files. The system gives the user (1) flexibility in defining and using data bases, (2) a wide range of procedures to be applied to the data, and (3) a variety of acceptable…

A description is provided of a conceptual model for a data secure system. The discussion first offers a formal working vocabulary and next, using the intuitive idea of a dichotomy between permissible and impermissible accesses, formalizes the idea with an Extended Logical Data Base and with protection specifications and patterns. These…

The publication of papers describing activity in computer-based storage and retrieval and geoscience information has continued at a vigorous pace since release of the last bibliography, which covered the period 1946-69 (ED 076 203). A total of 211 references are identified, nearly all of which were published during the three-year period 1970-72…

Describes a public library's newspaper index which provides unique genealogical and historical information, and supplements or replaces lost official records for local counties in the form of a printed index. The process of database design, staffing, software and hardware requirements, working with a programmer, and data entry are explained. (EM)

Discusses downloading of data from databases using microcomputers and mass storage technologies as it relates to copyright laws and legal implications.

Addresses the question of whether interest in downloading into local electronic libraries is a reflection of user needs or is being generated by those who have something to sell. Growth of online services, growth of local computer capacity, purposes of a local electronic library, and sources of data are highlighted. (EJS)

This article discusses sources from which information used in in-house databases can be obtained and enumerates points to consider in database building phase (test database design ideas against external database if available, make arrangements for data entry, exercise quality control). Fourteen contractors or sources of computerized information…

Explores the possibilities of using videodisc and optical disk technology as publishing media, highlighting the videodisc as an educational tool and visual supplement to online databases, digital database publishing on videodisc, optical disks for electronic document and image delivery systems, and costs associated with videodisc design and…

Describes the use of a microcomputer system to generate a personal database of books read by adding titles, displaying title/author information, and editing title/author information and discusses the system design, i.e., file structure (author index, book index, book, author), the main driver, function subroutines, and screen subroutines. (EJS)

Substantial alterations to a system often have little or no effect on particular collections. This may be due to poor separation of relevant and non-relevant documents. The paper presents a procedure for characterizing this separation, which can show whether proposed modifications of the base system are likely to be useful. (8 references)…

Retrieval performance with automatic term classifications for three test collections has been variable. This paper attempts to discover why. The real difference between the collections is in the separation of relevant from non-relevant documents. The separation is so poor that classification cannot be expected to succeed. (14 references)…
