- A Model for Library Book Circulations Incorporating Loan Periods. Burrell, Quentin L. Fenton, Michael R. Academic Libraries Higher Education Library Circulation Library Statistics Mathematical Formulas Models Statistical Distributions Tables (Data) Proposes and explains a modification of the mixed Poisson model for library circulations which takes into account the periods when a book is out on loan and therefore unavailable for borrowing. Highlights include frequency of circulation distributions; negative binomial distribution; and examples of the model at two universities. (Contains 34 references.) (LRW)
