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 any literate person, without special training, to ultimtely obtain access to all available public information stored in any of the multitude of online and videotext systems. It would also use broadcast videotext for current information; topical and index updates; and, for cable systems, TV programs could also be stored during the night on videodiscs. HUC is so structured that as voice command systems develop, the user can use the system without a keyboard. The paper details the assumptions and principles of the HUC concept; a unique identification system; index structure; unified software; terminal hardware; mass density storage; system configuration; and the benefits and applications of the system.
