A survey is made of the more important technological and managerial problems in the planning of university library services and recommendations are made for a positive program of innovation and development. Two approaches are explored in considerable detail. The first is the use of operations research models of the acquisition and storage functions. Elementary models and decision rules, based on the assumptions of exponential growth, independence of item usage, and obsolescence, are used to minimize average costs of circulation and to suggest more general models for library services. This is an exploratory study of the problems in library planning. This report does not pretend to offer a definitive statement on the subject; it does not provide any well-tested models, data for the design of library systems, or a thorough analysis of jointly dependent items. It does attempt an assessment of the current state of the art and to identify some promising and different directions for the development of planning criteria and techniques of analysis. (Author)
