It is the purpose of this paper to explore the use of extracts by reporting the results of a survey of the current acceptability and use of extracts, by a literature review and by suggesting guidelines for selecting extract material. The survey shows that extracts are currently being used in information services, especially for current awareness.…

The development of scientific journals in Japan pertinent to chemistry is reviewed, and the current status of abstracting activities in Japan is described. (Author)

The first volume in a series of publications describing the basic documentation practices involved in the initial setting up and subsequent operation of an information-library organization to provide defense-aerospace scientific and technical information services, this manual consists of three sections. "Acquisition and Sources," by…

Reports on study analyzing 13 abstracting and indexing (A&I) operations in order to ascertain those steps in specific processes that added value (i.e., were of benefit to user in making choices from information displayed). The user-driven/value-added model and a summary of value-added processes in A&I services are highlighted. (11…

To support studies in automatic indexing, classification and extracting, a general purpose frequency program was developed to further theoretical and practical understanding of text word distributions. While the program is primarily designed for counting strings of character-oriented data, it can be used without change for counting any items which…

This preliminary report of research conducted at the Linguistics Documentation Centre of the University of Ottawa describes a bilingual experiment into the elaboration of well structured formulary routines for making the writing of abstracts easier, and at the same time standardizing and generally augmenting the information given in them. The…

The report very briefly summarizes the research performed during the contract period March 1, 1964, to February 28, 1971. The emphasis of the research was on the discovery and development of techniques for automatically indexing and classifying documents. The research was limited to statistical techniques rather than semantic or syntactic. A…

The problems of information handling in education and a description of the techniques used to meet some of these problems are discussed. (Editor/KE)

The abstracts obtained so far are of sufficiently good quality to indicate that large-scale testing of the methods of the automatic abstracting system is warranted. (Author/MM)

In order to compare effects of input processing on information retrieval in three databases, 25 articles from a specific journal were examined. Tables and Venn diagrams show retrieval results from different manual and computer searches. The relation between document surrogates and subject matter of the documents is discussed. (SW)

Examines the "functional sentence perspective" theory, working with the concepts of the "theme" and "rheme" of a sentence, and analyzes possibilities for its implementation in the theory of information systems, particularly with respect to the study of so-called thematic progressions in and general structural formula of the text. (Author/CWM)

A task of regional educational laboratories is to provide information to state and local education policy makers. The new focus on policy reflects a change in the labs' knowledge base and audience. The subsequent move into the political arena has created risks for the labs, which have responded to the new task in different ways. The nature of the…

IMPLEMENTATION OF A NATIONAL OR REGIONAL NETWORK OF BIBLIOGRAPHIC INFORMATION WILL REQUIRE A BASIC STANDARD FOR THE IDENTIFICATION AND REPRESENTATION OF THE ELEMENTS IN THE DATA BASE. THE PURPOSE OF THIS SPECIAL PROJECT, DONE FOR THE SUBCOMMITTEE ON MACHINE INPUT RECORDS, WAS TO PROVIDE THE SUBCOMMITTEE WITH BACKGROUND INFORMATION WHICH WOULD BE…

The main purpose of this report is to help novice reviewers accelerate their apprenticeship at the Nuclear Safety Information Center, a computerized information service sponsored by the U.S. Atomic Energy Commission. Guidelines for reviewers are presented in Part 1; Part 2 contains guidelines for the novice editor. The goal of the reviewers and…

At present not-for-profit information accessing services play a unique role in the information transfer process as they provide long term discipline-oriented access to the subject content of individual primary published documents regardless of country of origin, language, or subject emphasis. While not all of these services are U.S. based or in…
