Two systems, WLN and Ringcode, for retrieving structural information were analyzed qualitatively and evaluated for a series of chemical compounds. The studies ranged from specific to generic questions and also involved retrieval by fragments. Neither system was completely satisfactory for all types of searches. (6 references) (Author)

An "answer-passage" is a passage which is either answer-providing or "answer indicative." New text searching techniques for the retrieval of answer-passages are discussed. Appendices listing thesauri, glossaries and dictionaries, syntactic joints, and connector words are included. (31 references) (Author/RS)

Implications of research findings comparing structural characteristics of two data bases for the development of screening systems for substructure search are set out. (4 references) (Author/SJ)

This brief article concerning the development of the network of educational documentation centres in Arab countries is followed by a list which includes addresses of the centres. (SM)

Pollution of natural resources such as information is the result of inefficient use of those resources and misplacement of those resources after use. Information workers must make judgements or assign priorities to information to ensure its use to serve the cause of a humane rationality. (1 reference) (Author)

A little understood aspect of implementing on-line software is the problem of effective monitoring. Northwestern University has developed techniques to monitor an on-line information retrieval system, by using that system both to monitor itself and to process the data collected. The Remote Information Query System is a batch and on-line…

The personal literature search of a scientist is strongly governed by subjective influences. If he delegates his query, he must be aware of the problems emanating from this subjectivity. The information scientist, on the other hand, must consider the subjective character of the fundamental notions of information and order. (33 references)…

An International Serials Data System (ISDS) is being established within the framework of UNISIST--a world science information system. National and regional centers will supply input on new titles to the register and act as a link between the international center and individual users. (4 references) (Author)

An interview with Robert E. Horn, the originator of information mapping, which is a technique that attempts to be a comprehensive design and presentation technology for making communication, especially learning and reference communication, easier and quicker. (GB)

A uniterm keyword system is explained which is thought to be suitable for small information centers operated by a staff of one or two. (3 references) (Author)

This paper sets the ERIC information system in the context of the more general characteristics and problems of social science information storage and retrieval. Social science information studies and attempts at organizing social science information are surveyed. (75 references) (Author)

The general finding is that task and socioemotional information flowed relatively freely across geopolitical boundaries within the three general geopolitical subsystems represented in the sample of theoretical high energy physicists. (29 references) (SJ)

Criteria used by the Information Services Department in deciding on the feasibility of proposed computer applications are reviewed. Natural trends in the development of information systems are described. Suggestions are made for increasing the probability of developing a successful application and for insuring that subsequent applications will be…
