Mechanism for changeable sheet books, especially for computer lists, characterized essentially by comprising a base plate and an upper plate of dihedral configuration, articulated by their corresponding parts to the outside of the book, presenting the base plate, in the central part of its dihedral space, a laminar vertical element held by its base and with a limited elasticity, forming on its head a conjugate flange of a longitudinal slit in the middle part of the upper plate, defining together a system for closing and retaining the mechanism in closed book position.
