A new articulated cover for changeable sheets, characterized in that it is made up of two parts, of which one is the lid 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, which embraces the edge of the lid, holding it firmly, being joined and articulated this piece to another of approximately rectangular section but with curved sides, effecting the union of one and another piece by means of an element formed by a cylindrical body, which is inserted at the end of the referred U-piece, and by a hook that is inserted at the end of the other, making the union above and below, so that the two pieces they are perfectly joined and the one that has a U shape and holds the lid, can turn on the other when the book is opened.
