The American Institute of Physics Current Physics Information program offers new products to help scientists and engineers stay up to date, including a computer tape file and microfilm cartridge of selected articles. Later additions will include title, advance abstracts and bibliographic publications. (TS)

The Index to Dental Literature" is evaluated in terms of its classification system, its standardization of nomenclature, its use of cross references and its effectiveness in machine-searching for information. (Author)

This paper is aimed at the extension of some results obtained so far concerning information systems design based on qualified parametrical relations. (Author)

The virtues of interactive systems are speed, intimacy, and - if time-sharing is involved - economy. The major problems are the cost of the large computers and files necessary for bibliographic data, the still-high cost of communications, and the generally poor design of the user-system interfaces.

An assessment of four important collections in the library revealed a need for better book arrangement and a systematic approach to improve accessibility and to stimulate browsing. (Author)

Intellectual questions that must be solved jointly by librarians and scholars concern the optimum amount and character of the literature that requires library preservation throughout the world, in this country, and within a particular institution. (MF)

A concept of a catalog that is hospitable to mechanized descriptive cataloging is presented, together with four areas of research programs that will yield findings useful in the development of such a catalog. (Author/JB)

Nine experiments involving fourth-year British comprehensive school pupils revealed that (1) text headings aided information recall, search, and retrieval from texts; (2) the position of the heading (marginal or embedded) had no effect; and (3) the kind of heading (question or statement) had no differential effects on readers of different ability.…

This editorial addresses the issue of whether or not to provide free-text, keyword/boolean search capabilities in the information retrieval mechanisms of online public access catalogs and discusses online catalogs developed prior to 1980--keyword searching, phrase searching, and precoordination and postcoordination. (EJS)

This discussion of the major issues concerning online public access library catalogs highlights types of systems, user behavior, structure of systems and user-friendly information retrieval methods (menus, fuzzy matches, prompters), and additional search strategy features (limits, browsing, truncation). Three references are listed. (EJS)

Focuses on the development of citation analysis as a research method, critiques of citation analysis, applications (both as tools for librarians and tools to analyze research activity), and prospects for the future. One hundred references are provided. (EJS)

Issues having a possible impact on online search services in libraries are discussed including full text databases, front-end processors which translate user's input into the command language of an appropriate system, downloading to create personal files from commercial databases, and pricing. (EJS)

Mathematical concepts used in modern algebra are shown to be useful in modeling syndetic structure employed in information retrieval systems. The equivalence relation can represent "see also" components of traditional library catalogs; partial orderings and mappings assist in modeling syndetics in sophisticated systems such as thesauri.…
