As an exploration of the frustration experienced by users of an on-line interactive retrieval system, students participated in an experiment using an experimental reference retrieval system for library literature. It was anticipated that significant variations in user behavior would be displayed by the control and experimental groups. (19…

Methods for retrieval of information on chemical compounds utilizing several computer data bases are compared to determine scope of data base coverage. Preparation of search questions is outlined and comparative results are reported indicating the yield from each data base. (6 references) (Author/NH)

The philosophy of a systems approach to the design of information storage and retrieval systems is suggested in which the computer is recognized in its proper perspective as a powerful and effective alternative tool. (Author)

Subcommittees of the Committee on Information Hang-Ups concern themselves with attempting to break down the barriers between the user and the information he seeks. This report discusses the problems encountered with the use of microforms and especially with the use of microfiche. (Author)

An experiment is described which attempts to define a quantitative methodology for the identification and evaluation of all possibly relevant periodical titles containing toxicological-biological information. A statistical decision model was designed and employed, along with yes/no criteria questions, a training technique and a quality control…

Northwestern University's Remote Information Query System (RIQS), an information storage and retrieval system characterized by a mixture of data structures for the internal record organization, is discussed. On-line and batch mode search capabilities handle both textual and quantitative information. Other system characteristics, capabilities and…

Experiments reported here were designed to investigate the drive known as epistemic curiosity which Berlyne had previously demonstrated by showing that subjects given a questionnaire and then a set of statements including answers to the questionnaire recalled more of these answers than subjects not given the questionnaire.

This analysis of attention and learning shows that a modified version of the one-look model not only can predict one- and two-cue learning, but can also accommodate the major results of the relevant redundant cues literature. (Authors/MB)

The major topics included in this paper are: thesaurus structure, later developments, functions of thesauri, keyword list generation, compatibility, and maintenance and updating. (NH)

A Pathfinder functions as a step-by-step instructional tool which introduces a library user to the variety of information sources availabel in research libraries. (Author/NH)

Four operational systems for searching and retrieving information from the ERIC data base are described. (NH)

Computer programs have been written which enable substructure searches to be carried out on a file of compounds ciphered using a modified version of the IUPAC (Dyson) notation. The search system outlined is to be linked with one which uses input from the chemical structure typewriter. (3 references) (Author)

Paper presented before the newspaper Division at Special Libraries Association Conference (Montreal, June 1969). A pilot program at Medill School of Journalism, Northwestern University, uses Microfilm Retrieval Access Code (Miracode) for rapid automatic searching of newspaper clipping files. (Editor/JS)
