The purpose of this study is to clarify the relation of each corner and the location of browsing corner for adult's multipurpose uses at public libraries. The results are as follows; 1. About half of the adults use not only books, but also magazines and audio visuals. We call them multipurpose uses. Especially, the use of both books and magazines is more than 50% of them. Therefore, it is necessary to locate the maeazine corner near the adult's book corner. 2. It is necessary to locate the browsing corner in the book corners. The number of seats needed for browsing is 70 to 80% of the greatest number of the book corner users. Many adult users browse most in the seat only 3m from each book shelf.
