TL;DR
A simple model of a two-stage hierarchical library system is described and it is shown that the viability level of stock provision of the branch library is determined by the ratio of the two actual user costs, rather than the actual costs themselves.
Abstract
A simple model of a two-stage hierarchical library system is described. The model indicates, in terms of "user costs" and library "viability", how the branch library should be stocked. The most significant factor used in the analysis is shown to be the ratio of the two actual user costs, rather than the actual costs themselves. It is shown that the viability level of stock provision of the branch library is determined by this ratio.
