This is the authors' abstract. We don't add key points for this paper.
The effective planning of technical libraries would be greatly facilitated if there were some theoretical basis which could be used to predict the probable distribution by titles, and by age of journal, of future journal demand. As a first step, the author has recently developed a general expression for the distribution among journal titles of large groups of journal references. In this present paper a relationship between usage and age of journal is established and the application of this relationship to some library planning problems is illustrated.
