After three years of preparation, the Project Intrex research team has begun to subject parts of its augmented catalog system to interactions with users who were interested in the substance of the stored information and uncontaminated by prior association with the Intrex research effort. The experiences with users to date, as well as progress made…

An outline is presented for a digital computer simulation model for an information network for the State of California. The methodology of simulation is discussed initially. The problems presented by the very large size of the system, in terms of materials, users, communication connections are depicted, and solutions are suggested which permit…

Reviews three types of online bibliographic retrieval studies: evaluation studies, including online service costs, manual versus online searching and vendor comparison; use and user studies, examining various populations; and projects designed to improve user access and user aids, such as vocabulary search aids and inter-system compatibility.…

REACTIONS OF A USER POPULATION (SCIENTISTS/ENGINEERS AND LIBRARIANS) TO AN OPERATIONAL TEST OF AN ON-LINE SYSTEM FOR RETRIEVING DOCUMENT CITATIONS (RECON) WERE STUDIED AT SEVERAL NASA FACILITIES. DURING A TWO MONTH OPERATIONAL TEST PERIOD, DATA WERE COLLECTED REGARDING FREQUENCY OF USAGE AND DEGREE OF SUCCESS ENCOUNTERED IN CONDUCTING ON-LINE…

A feasibility study examined the capability of a computer-based system's handling of technical information pertinent to the design of instructional systems. Structured interviews were held to assess the information needs of both researchers and practitioners and an investigation was conducted of 10 computer-based information storage and retrieval…
