This report explains the following mathematical techniques which may be used for relating search requests to documents contained in a library: (1) Boolean Algebraic Retrieval, (2) Linear Statistical Retrieval, (3) Statistical Association Techniques for expanding a query and/or for expanding the set of retrieval documents, (4) Vector Space…

In times when the total volume of information is proliferating and information users are demanding greater access and faster response, the librarian is likely to turn to the computer for assistance. Modern computers can provide fast, accurate operations with an enormous capacity for bibliographic data, and they can be accessed through on-line,…

A citation study investigated the coverage by abstracting and indexing services of literature dealing with the environmental effects of the forest and forest products industries, the impact of man on the forest ecology, and methods for maximizing forest tree utilization. A search of nine secondary sources (abstracting and indexing services)…

A pilot study to develop a feasible multi-media index to regional material has just been completed. Its primary objective is to develop a tool for general user access to information in various formats by combining old and new methods and techniques of information retrieval. Simple computer programs manipulate the information on 106 sample items to…

This document discusses problems and methods of language classification, especially with regard to questions of information storage and retrieval in connection with an information network for the language sciences such as that envisioned by the LINCS (Language Information Network and Clearinghouse System) Project at the Center for Applied…

In order to carry out its project for a mechanized documentation service based on a system of keyword coordination, European Atomic Energy Community's Centre for Information and Documentation was led to draw up an inventory of terminology in the nuclear field and maintain a tight control over it. A basic thesaurus of 1230 keywords was drawn up 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…

This is the fifth in a series of eight reports of a research study for the National Agricultural Library (NAL) on the effective utilization of bibliographic data bases in machine readable form. NAL desires ultimately to develop techniques of interacting with other data bases so that queries put to NAL may be answered with documents or document…

Reported are the findings of the Uspekhi experiment in creating a labeled machine file, as well as sample products of this system - an article from a scientific journal and an index page. Production cost tables are presented for the machine file, primary journals, and journal indexes. Comparisons were made between the 1965 predicted costs and the…

This Noun Reference Dictionary is divided into two sections: nouns derived from verb roots and those not so. The following features are noted in each entry: (1) class index; (2) occurrence in idiomatic expression; (3) part of speech; (4) declinability; (5) occurrence with prefixes "B,""K,""L," and "M," or…

This document comprises the second part of the pure nominal section of the Noun Reference Dictionary. See AL 002 267 for the first part, and AL 002 269 and AL 002 270 for the verb root-nominal sections. ED 019 668 and AL 002 296 contain a description of the project. (DO)

The Institute on the Automation of Bibliographical Services was held at the University of Maryland, 10-21 June 1968, conducted by the School of Library and Information Services, assisted by the Library of Congress Information Systems Office and the University Computer Science Center. Thirty-nine participants from academic, special, and public…

The first section of this report contains a short summary of the papers and proceedings of this Conference which was initiated and directed by the University Library and sponsored by the Library Education Division of the American Library Association. Ten working papers were distributed prior to the Conference and served as a background to the…

Two overall levels of bibliographical control are desirable: one should be as complete as possible; the other should be a selection of prime items whose titles are organized for ease and effectiveness of consultation and decision making about the texts which are worth looking up; and this selection should be the aim of a complementary computer…

Libraries, as well as larger information networks, are necessarily based upon the storage of information files consisting in many cases of written materials and texts such as books, serials, abstracts, manuscripts and archives. At the present stage of the "information explosion" no librarian can afford to ignore the contribution of…
