Historical notes are also provided, as well as biographical information on the authors of individual articles in this special section. (16 references) (CLB)

This paper proposes a user designed system, HUC, intended to provide a single index and retrieval system covering all recorded knowledge and information capable of being retrieved from all modes of storage, from manual to the most sophisticated retrieval system. The concept integrates terminal hardware, software, and database structure to allow…

A new search feature has been developed and implemented to enhance online information retrieval from the ABI/INFORM database, which includes abstracts from more than 500 journals covering all aspects of business and management. Published by Data Courier Inc., it includes material dating back to 1971. Because of the diverse nature of the database…

User perception of data importance and the economic feasibility of hardware and storage devices will determine the future direction of online systems. A retrieval system's functions are ultimately dictated by database design. Early online sytems were designed for bibliographic information limited to citations only using sequential files. When…

Discusses the need for knowledge gateway systems to provide access to scattered information and the use of technologies in gateway building, including artificial intelligence and expert systems, networking, online retrieval systems, optical storage, and natural language processing. The status of four existing gateways is described. (20 references)…

Examines a multiplicity of issues that must be considered as features are taken from two existing systems--libraries and computing centers--and used in moving toward the integrated information support system of the future. Discussion covers indexing, conversion, access, security, costs, changes in the workplace, and challenges of transition. (EJS)

A series of six articles discusses the technology of optical data disks, current and possible future applications of this technology, their potential impact on information retrieval systems, and the potential problems as they apply to information science. (CLB)

This report is intended to assist Canadian libraries in assessing potential library applications of optical disk technology. Part 1 provides a general outline of the technology and describes a number of library applications and projects. Descriptions are purposely general and illustrative in nature since the technology and its applications are…

A series of 11 articles describes information technologies being used in the U.S. Congress, the impact of these technologies, and possible future developments. Included are a chronology of key actions affecting congressional information support and a list of readings in information technology and Congress. (CLB)
