Describes a longitudinal study of students' perceptions of the information search process in libraries over a four-year period from high school through college. The discussion covers the cognitive theory on which the study was based, a model of the search process, and how closely students' perceptions matched the model. (26 references) (Author/CLB)

Outlines procedures for selecting scientific journals for academic library collections and provides a model which ranks data sources according to their relative weights rather than ranking the journals themselves. Use of the model in scientifically less developed countries is discussed. (Author/LRW)

Discusses importance of academic planning and describes a model-based decision support system for academic units in a university hierarchy. This system integrates macro-level decisions by examining individual departments' budgets to determine future plans. Quantitative techniques for forecasting change are reviewed, including use of spreadsheet…

Examines how informetric characteristics of information retrieval (IR) system databases can be used to help system designers decide what type of file structures would provide the best performance. The development of appropriate models describing database contents is highlighted in this first part of a two-part study. (30 references) (LRW)

This second report on a two-part study on the application of informetrics to information retrieval (IR) system design used models of database contents in a factorial simulation study at the University of Western Ontario. The study explored whether different file structures were better suited for different informetric environments. (32 references)…
