PROBLEM TO BE SOLVED: To provide a book (magazine) divertible to loose-leaf one wherein a cutting line of perforation making it possible to divide and separate one part of a paper sheet surface, while leaving the other part behind, is provided in a gutter-space-side portion of the surface, while holes enabling filing of the paper sheet by a binder are provided in an edge-side lateral part of the perforation or an edge-side end of a page, in order to reduce a burden of the weight in carrying the book (magazine) or a spatial burden in storage and to save the labor of cutting off the page in the book (magazine) and storing it. SOLUTION: In the book (magazine) divertible to the loose-leaf one, the cutting line of the perforation making it possible to divide and separate one part of the paper sheet surface of the book or the magazine, while leaving the other part behind, is provided in the gutter-space-side portion of the paper sheet surface, while the binder holes are provided in the lateral part of the cutting line of the perforation (on the edge side).
