Two essential components of the information-logic problem are: (1) choosing some known part of the total information block for parallel review of the entire block and (2) parallel logic processing of a sequence of codes. The described device fulfills these essential components thereby improving information processing and increasing the speed of…

In setting out to design a system of cataloging, or to evaluate a given system, or to apply a system in effect, it is necessary to begin with a clarification of the ends which the product of cataloging - that is, the catalog - is to serve in the library. To contribute to an understanding of these ends, the present study considers the role of the…

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…

A storage and retrieval system for chemical structures, using optical coincidence, is in use at Schering Corp. The system rapidly provides the research laboratories with structural information at any generic level. The design, maintenance, costs, and applications are discussed. (4 references) (Author)

A brief introduction to information retrieval by use of a variety of computer data bases including ERIC is presented. (JMF)

This research sought to distinguish among three concepts of visual persistence by substituting the physical presence of the target stimulus while simultaneously inhibiting the formation of a persisting representation. Reportability of information about the stimuli was compared to a condition in which visual persistence was allowed to fully develop…

The papers and discussions of the 1975 Pacific Region meeting of the Association for Computing Machinery are presented. Topics included (1) the current and emerging state of the art in data management software and hardware, (2) relational systems with particular attention to new developments in systems for relational data bases, (3) advances in…

Utilizing both the experience gained from the Machine-Readable Cataloging (MARC) Pilot Project, which tested the feasibility of distributing Library of Congress cataloging in machine readable form to various users, and the results of extensive consultation with the library community and persons at the Library of Congress, a format for…

A description is given of the RAIDS (Rapid Availability of Information and Data for Safety) method of information storage and retrieval. Acquired data are stored in the library in its original printed form. RAIDS provides three approaches to the identification and retrieval of data. The first approach is to organize the information into logical…

TRIAL is an information processing system that will perform editing, indexing, and retrieval of textual and certain types of numeric information. The system allows for: (1) the creation and maintenance of a master file, (2) indexing on words designated as 'key' words or, alternatively, on every word in the text, excluding those common terms that…

As part of the report on the California State Library Processing Center (CSL-PC) design and specifications, this volume covers: (1) file maintenance, a discussion of updating system files with new entries and MARC tapes; (2) authority verification, the correction and standardization of subject headings and author names; (3) the filing system for a…
