The Cambridge Crystallographic Data Centre is concerned with the retrieval, evaluation, synthesis, and dissemination of structural data obtained by diffraction methods. This paper describes the use of a computer-based file system of both bibliographic information and numeric data to produce a compendium of interatomic distances. (10 references)…

A new, universally applicable computer program is described for the whole complex of punched card oriented literature documentation. Its characteristics are: modular construction, therefore easily adapted to user-specific problems; extremely high searching capacity; comprehensive and elastic syntax makes possible new unconventional methods of…

The present installment continues the updating service and supplements coverage contained in MMRI-1972. (Author)

This investigation shows that search keys derived from personal author names possess a sufficient degree of distinctness to be employed in an efficient computerized interactive index to a file of MARC II catalog records having 167,745 personal author entries. (8 references) (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 social sciences require multiple methods of analysis of information from complex data bases. Data bases have been constructed which contain hierarchical, spatial, and temporal associations among information elements. To provide effective processing capability an integrated approach was taken to facilitate storage and retrieval, statistical…

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 important factor to be considered in applying clustering techniques to information storage and retrieval problems is the use to be made of the resultant groupings. An examination of cluster criteria differentiation as a function of purpose may be fruitful in the exploitation of clustering techniques. (12 references) (Author/KE)

Three methods of picture storage and retrieval used in collections without automatic data processing facilities are discussed in two parts. Part I covers self-indexing files which can be used for portraits, geographical pictures, things, plants, animals, and events. Part 2, will discuss individual cataloging and group cataloging. (2 references)…

A summary description of the information retrieval course in political science which is taught by the author at California State University, Northridge, California is given for the benefit of librarians who are setting up similar courses. (4 references) (Author/NH)

The data base coverage of these two services was examined and selected computerized searches performed. The results of this study provided some meaningful conclusions as to the general utility of these services. (3 references) (Author/NH)

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)

An informal survey was conducted, tapping the opinions of scientists doing research related to the features that should or should not be included in the man-machine interface of interactive bibliographic search and retrieval (IBSR) systems. An analysis of the responses showed a significant level of agreement concerning interface features. (2…

The question is asked: Of index terms assigned to documents, which function most effectively in retrieval, the most used or popular terms, or those which are used relatively infrequently? The experiment is a retrieval experiment and uses the Cranfield-Salton data. (14 references) (Author)
