Peer reviewedParker, Ralph H. – Journal of the American Society for Information Science, 1982
Develops an empirical model for predicting the size of an information store necessary to satisfy specified levels of demand. A method for selecting items for retirement with the least adverse impact on the store is suggested. Three tables, three figures, and a 10-item reference list are included. (Author/JL)

Peer reviewedParker, Ralph H. – Journal of the American Society for Information Science, 1982
Uses bibliometric techniques in the development of a model of the distribution of demand for items in an information store. The hypothesis of hyperbolic distribution and an index of differential demand are also discussed. One table, two figures, and a 10-item reference list accompany the text. (Author/JL)

Peer reviewedParker, Ralph H. – Journal of the American Society for Information Science, 1982
Examines the distribution of use of items in a large information store and suggests that a simple exponential model describes the process of obsolescence more precisely. Three tables, four figures, and a 17-item reference list are included. (Author/JL)
