The series of this reports is to be tried to get the characteristics of the loan flow in a public library's network of metropolis. The flow is drawn by smoothing lines that are computed by Iterated Moving Average Method. This study is to seize the influence of the existing libraries' flow by openning of the adjacent new library. In this study, I could find out the interesting flow, when it is affected by the impact (not strong) of openning. It draws sometimes the U-line like the locus when a bowl bounds once.
