Abstract
The correlation structure of the Burrell and Cane mixed Poisson model for library loans with ageing is presented and is illustrated by data from the University of Sussex. The approach is compared and contrasted with that originally formulated by Morse and most recently re‐evaluated by Beheshti and Tague. Directions for future investigation are suggested.
