Perfected notebook, of the type in which the fastening of leaves and cover is achieved by a spiral, characterized essentially because the sheets, close and parallel to one of its edges, have at least one pair of holes of adequate dimensions to the thickness of the rings of a conventional filing cabinet, and because parallel and close to the spiral, each of the sheets presents a line of breakage that defines, once the leaf detached from the spiral, the size of the same.
