Abstract
A new removable cover for books with changeable sheets, characterized in that it consists of two parts: one of which is the cover itself, and another the device that holds it and rotates it when the book is opened, this device being constituted by a piece whose section has an approximate U shape that embraces the edge of the lid, and holds it firmly, resting this piece on another of rectangular shape and ends of a curved side, to which it is attached by means of the tapes that hold the pages of the book, through the quadrangular holes of which both are provided, in the same point of coincidence.
