Stewart, Mark; Willett, Peter – Journal of Documentation, 1987
Describes the simulation of a nearest neighbor searching algorithm for document retrieval using a pool of microprocessors. Three techniques are described which allow parallel searching of a binary search tree as well as a PASCAL-based system, PASSIM, which can simulate these techniques. Fifty-six references are provided. (Author/LRW)

Macleod, Ian A.; And Others – Information Processing and Management, 1987
Discussion of the need for distributed information retrieval systems focuses on a model system, Fulcrum FUL/Text. Differences from distributed database management systems are described; system design is discussed; implementation requirements are explained including remote operation calls (ROC's); and a prototype simulation model based on FUL/Text…

Newby, Gregory B. – Proceedings of the ASIS Annual Meeting, 1993
Discussion of virtual reality (VR) focuses on the promise that VR offers for information systems by describing current systems which use VR and by projecting possible developments for the future. Types of information problems which could be helped by VR are considered, as well as those that could not be helped. (Contains 13 references.) (LRW)

Oswitch, Pauline – Library and Information Science Research, 1983
Describes British Library's work on Systems Dynamics, a set of techniques for building simulation models based on analysis of information feedback loops. Highlights include macro-simulation modelling activities of social science disciplines, systems analyses and models of information retrieval processes and library services, policy models, and…
