Of the problems discussed, those posing the greatest obstacle for the full utilization of microform systems are: (1) the problem of identifying the material on microforms when it is associated with key words in computerized digitalized systems; (2) the problem of copyright in converting collections of material into microform stores; and (3) the…

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…

There is little justification for research activities unless some plan is formulated to utilize their results. Consequently, a conference comprising representatives of rehabilitation agencies in the Southeast was held during June, 1968 to review ways and means of disseminating, retrieving, and utilizing research and demonstration results. The…

Formal proofs are given of the effectiveness under well-defined conditions of the thesaurus method in information retrieval. It is shown, in particular, that when certain semantically related terms are added to the information queries originally submitted by the user population, a superior retrieval system is obtained in the sense that for every…

Many of the techniques used to structure, record, and store information contained in printed material should now be applied to the field of audiovisual media. The rules of communication and association which apply to printed knowledge can serve as tools to critically analyze messages delivered via audiovisual media. This text describes the…

Past problems encountered in the use of computers are discussed. They include: (1) computing and data storage costs; (2) machine speed and capacity limitations; and (3) the limited number of languages and Input/Output devices available to facilitate man/machine communication. The improvements in all of these areas are explained. The problems which…

Organization of communication between the center of an automated system of information exchange and the subscribers to the system is described. The three requirements are: (1) those technical communication means must be chosen which will provide effective and convenient avenues for calls from the subscribers to the center, (2) the required…

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…

Subjects covered in this bibliography include manual, mechanized and automated techniques, evaluation of systems, standards, storage and retrieval systems, research, vocabularies, author participation, permuted title indexing, citation indexing, and specialized indexing requirements, i.e. chemistry, medicine, patents, engineering drawing, and…

This report describes implementation and exercising of simulation models for a portion of user behavior in the library setting. The emphasis is on user estimations of timing and convenience factors of service and how these are affected by actual service. The report begins with an oversimplified view of the user and becomes progressively more…

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…

Although the indispensibility of access control mechanisms in data secure systems has been recognized, there is a need for more subtle protection and refined control mechanisms. This report describes context protection mechanisms which enable the same data unit to be protected differently in different contexts, the differences being determined by…

This report discusses SIGI, an operational example of a computer-based career guidance system. The system demonstrates that such a service can be performed well and at a cost within the reach of most schools. Data collected during the pilot trail indicate that students who had used SIGI were more aware of the career options open to them and the…

Three projects, each covering certain selected aspects of a potential information storage and retrieval system, were part of a study by the Ontario Educational Communications Authority (OECA) to explore various means for extending the usefulness of audiovisual materials. Project Dataset began the collection, classification, and cataloging of…
