An experiment was conducted to identify some of the important parameters affecting search time, a critical cost factor in retrieval systems. Using actual computer searches of Chemical Abstracts Condensate, a comparison was made between the effectiveness of linear and inverted filing systems. Since the results indicated that it was the type and…

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…

INFOL for the CDC 6400 is a rewrite in FORTRAN IV of the CDC 3600/3800 INFOL (Information Oriented Language), a generalized information storage and retrieval system developed by the Control Data Corporation for the CDC 3600/3800 computer. With INFOL, selected pieces of information are extracted from a file and presented to the user quickly and…

Large-scale, on-line information storage and retrieval systems pose numerous problems above those encountered by smaller systems. A step toward the solution of these problems is presented along with several demonstrations of feasibility and advantages. The methodology on which this solution is based is that of a posteriori automatic classification…

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…

A description is provided for WISE-ONE, an information retrieval program designed to provide fast, efficient access to computer-based information files. The author focuses upon WISE-ONE's application to the Educational Resources Information Center's (ERIC) data base; WISE-ONE was designed specifically to meet the needs of researchers using ERIC,…

The characteristics of the Intrex subject/title inverted file are analyzed. Basic statistics of the inverted file are presented including various distributions of the index words and terms from which the file was derived, and statistics on stems, the file growth process, and redundancy measurements. A study of stems both with extremely high and…

The design of an English-like query language and an interactive computer environment for searching the full text of the U.S. patent collection are discussed. Special attention is paid to achieving a transparent user interface, to providing extremely broad search capabilities (including nested substitution classes, Kleene star events, and domain…

Textbooks currently in use in courses on information science are listed in this bibliography under the following headings: Information storage and retrieval, Information systems, Information theory, Behavioral sciences, and Basic books. Some of the entries in each category contain evaluative annotations by the author, while others have only the…

In pursuance of resolution 2.141 (a) adopted by the General Conference at its sixteenth session (October-November 1970), the Intergovernmental Conference for the Establishment of a World Science Information System (UNISIST) was organized by Unesco. The purpose of the Conference held October 4-8, 1971 was to make recommendations covering the basic…

It is the purpose of this study to provide fresh insight into the nature of library problems by systematically studying the question of size in various information contexts. In the introduction, the role that size plays from the user's point of view is illustrated. In the following sections, a study of the card catalogue, the classification system…

OCCUPATIONAL INFORMATION SERVICE IN GUIDANCE FOCUSES ON THE DIFFERING NEEDS OF HIGH SCHOOL STUDENTS FOR KNOWLEDGE OF OCCUPATIONS. OCCUPATIONAL INFORMATION IS DEFINED AS ACCURATE, UP-TO-DATE TREATMENT AND INTERPRETATION OF DATA IMPORTANT TO THE PROCESS OF OCCUPATIONAL SELECTION, PREPARATION, PLACEMENT, AND ADJUSTMENT. TO MEET THE NEED FOR SUCH…

Defines forms and the processing characteristics of working forms, and introduces the proposed prototype form definition language to specify the information requirements and to describe the nonprocedural execution in activity processing. The article also outlines the integrated forms-based information system, focusing on the interactions among the…

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…
