The Library Systems have been developed so that the users can reserve, borrow and return books at any preferable libraries. For effective planning of libraries, it is necessary to evaluate the effectiveness of Library Systems. First, we analyze the time-space distribution of users behavior using the data on the number of books transported by users or administrators of libraries. Second, we analyze the variation of the number of visitors using the information on months, days and weathers. Last, through the survey on the actual users behavior of Yokohama City Libraries, we investigate the characteristics of multiple-facility use and examine the relationships between users behavior and regional features.
