Peer reviewed Peer reviewed
Hayes, Robert M.; Borko, Harold – Information Processing and Management, 1983
Presents results from study of mathematical models (Cobb-Douglas model, mixture of Poissons, inverse effects of distance, weighted entropy) relating to usage of information systems, and notes papers developed during study which provide three types of analysis--literature reviews, analytical studies, and tests of models. Six references are…

Buckland, M.K.; Woodburn, I. – 1968
A research project is being conducted to construct a mathematical model of the operations of an academic library to be used in making managerial decisions. As part of this project, this report examines Bradford's Law of Scattering and the fall-off of use of documents as they age. A series of mathematical analyses indicate how these two laws can be…
