| Abstract: | ??Compares the precision of two kinds of mathematical models of the relationship between the duplicates number of library collections and their borrowing times. It is proved that the relation curve has indeed a turning point, and it has a good ground to measure the optimum duplicates number of library collections on the curve. |
