This study determines annual book obsolescence rates for individual instructional departments within a university. Analysis o sue factors as immediacy and intensity of peak usage, use dispersion, and the commonality of use have helped to develop an acquisition priority weighting (APW) formula. The function of the APW is to serve as a guide in the collection development process. The Circulation Commonality Table, the Dispersion Table, and the Immediacy/ Intensity Table were used to refine the

This study identifies specifically which one-third of total resources receives two-thirds of total use, thus, the 1 13-2 /3 rule was developed.
