Abstract |
The purpose of this paper is to propose a new mathematical model for predicting theamount of loan at public libraries, and to investigate the validity of the model by usingstatistical data on public libraries at Saitama Prefecture in Japan. The model is L==aCPexp(一一 bC), where L is the number of times books are circulated in a library, C is the number of booksheld at the library, P is the population within the service area, and a and b are parameters. Themodel explains well statistical variation of the amount of loan at Saitama Prefecture. lt can besaid that the result shows a sort of “inverse effect” of size of collection or population, which isrepresented by exp (一一一bC) in the model, on the increase in loan. Also, a simple simulation basedon the model is tried to assess the effectiveness of new sites for access.
