Almost all disciplines make extensive use of the resources provided by slide libraries and picture collections. Growing demands for pictorial material have stimulated a concern for making slide and picture collections more useful and more usable by better physical arrangement and more thorough indexing. The system provides a classification scheme…

This research reports an algorithmic approach to the automatic generation of thesauri for electronic community systems. The techniques used include term filtering, automatic indexing, and cluster analysis. The Worm Community System, used by molecular biologists studying the nematode worm C. elegans, was used as the testbed for this research.…

A research project carried out a survey of operational software designed to produce printed subject indexes and measured the human and machine costs of producing such indexes. (PF)

An experiment in superficial indexing was carried out to elaborate the contract between indexing with a controlled vocabulary and using automated methods as described by Salton. (Author)

Reports research undertaken to conceptualize, design, and implement a system for automatic indexing, classification and repositing of "text items," which may be any aggregate of information in English Language on a computer-readable media, in a standard format. (Author)

The concept of tri-citation is introduced, as a logical extension of co-citation, and a geometrical model (the circle) is devised to account for these and all other forms of multiple citation. (Author)

An expansion of a list developed at a British library school, this glossary contains terminology used in indexing work done by libraries and information scientists. Entries are arranged alphabetically and vary in length from one line to one page. There may be up to three parts in each entry. The first is a basic definition with examples where…

Printed bibliographic descriptions of journal articles cited by BioSciences Information Service of Biological Abstracts (BIOSIS), Chemical Abstracts Service (CAS), and Engineering Index (Ei) were compared to identify similarities and differences in form, format, and data content. (Author)

Fees are charged by these services on the basis of flat rate, service, and "connect time." Support can also be obtained through subsidies. Some services market diverse products in addition to their printed publications, including output in different formats and document services. (JAB)

Experiments with two distinct collections, using three levels of indexing exhaustively for both documents and requests, show that substantially the same performance is obtained for very different levels of document indexing, if suitable choices are made of request level. (6 references) (Author)

Preparing decision makers for the future is discussed in terms of a three pronged approach to the teaching of document surrogation: Knowledge about, skills in, and management of. The management prong should include the habit of using the data from the present situation to make decisions about future change. (5 references) (Author)

An indexing system for chemistry and technology of macromolecular substances is sketched out, whose characteristics are convenience of use and low cost. The selection mechanism consists of a set of optical coincidence cards. The selection is a result of 15 years experience in the German Plastics Institute. (13 references) (Author)

Summarizes the historical development, functions, and changing nature of secondary information services, with emphasis on abstracting and indexing services. (JL)
