Presents uniform and efficient approach for processing all truncated query terms in information retrieval which requires one disk access to obtain from the permuted dictionary all strings represented by truncated term. The problem of the overhead storage required to implement the permuted dictionary is discussed. Fifteen references are provided.…

Effective management of movable equipment in a large institutional environment requires a readily accessible database containing accurate up-to-date information. The design and maintenance of an equipment database at the University of Illinois School of Chemical Sciences are discussed. (MLW)

Examines the development and current status of research on personal information systems, i.e., those systems where an individual collects, annotates, and stores bibliographic information according to his own needs and preferences. Effects of computer-based dissemination services on the growth and management of these systems are discussed. Included…
