Longman, Janet S.; Robson, Alan – Journal of the American Society for Information Science, 1976
It is shown that automatic search profiles can be derived which perform comparably with corresponding manual profiles. The most efficient automatic profiles, in terms of performance and search time, are those consisting predominantly of single terms enriched with fragments. (Author/PF)

Rose, Denis A. – Journal of the American Society for Information Science, 1983
Availability of low-cost digital optical disks will revolutionize storage and retrieval systems over next decade. Three major factors will effect this change: availability of disks and controllers at low-cost and in plentiful supply; availability of low-cost and better output means for system users; and more flexible, less expensive communication…

Hendry, David G.; Harper, David J. – Journal of the American Society for Information Science, 1997
Investigates how an informal computerized environment, or workspace, can support information seeking. Outlines the design space for information-seeking environments and presents a prototype, SketchTrieve, a graphic editor. Discusses how this environment might support information-seeking in ways not available in other more overdetermined systems.…
