The skeleton for a universal language for information retrieval is proposed. (NH)

Information Dissemination Centers have emerged as brokers or retailers for computer-based information retrieval services. Areas which concern users and suppliers are the nature of data bases available for search, retrieval results and factors affecting them, timeliness of services, cost and prices, and practical operational considerations related…

The search for an optimal decision strategy can be treated as a mathematical programming problem with linear objective function to be maximized over the convex set of certain functional space, provided one is willing to accept some ergodicity assumptions of the Markovian environment.

The on-line serials control system in use at the UCLA Biomedical Library is compared with former batch processing and manual procedures. It is evaluated in terms of performance, user satisfaction and costs, and is shown to be superior in these respects. The system makes possible increased productivity and savings.

The results of a questionnaire to determine art scholars' needs isolates areas in art bibliography and art librarianship that seem to be deficient. Specific bibliographic tools and an evaluation of art librarians are discussed. (12 references) (Author/DH)

Frequency theory of verbal discrimination learning holds that the correct and incorrect alternatives of each word pair acquire differential frequencies. (Author/MB)

Specific aspects of the thesaurus treated in this brief review are: thesaurus as a concept, classification and structure, and language compilation and control. (75 references) (NH)

Basic experimental design tested to see whether semantic shifts and variation of intertrial interval influences performance in short-term recognition memory in a manner similar to their influence in short-term recall. (Authors)

The on-line serials control system in use at UCLA Biomedical Library utilizes and inverted file for its primary retrieval technique. A detailed profile of title structure and search scheme is given. The major determinants of the scheme are evaluated on a performance and cost basis. (5 references) (Author/KE)

Primary purpose of this study was to investigate the processes underlying simple mental multiplication. (Author)

Some salient concepts derived from the information sciences and currently used in theories of human memory are critically reviewed. The application of automata theory is proposed as a new approach in this field. The approach is illustrated by applying it to verbal memory. (Author)

During research reported here, the author held a Fulbright-Hayes Fellowship. (VM)

Procedures for coordinate indexing are described and the importance of a controlled vocabulary common to indexer and searcher discussed. (Author)
