Index perfected for dictionaries, essentially characterized by arranged in the outer plane of the superimposed set of sheets and opposite to the spine of the corresponding volume, an indelible recording of each and every one of the letters that make up the alphabet, whose arrangement is made in oblique direction, corresponding the left zone to the upper one of the stacking of sheets and in the opposite direction in the lower one, which establishes a natural order of identification with provision of marks, on one of the sides of each printed letter and the same height as this, being these marks of equal height that the letters referred to and their thicknesses are variable in relation to the volume of sheets to which the initial of the printed words or terms corresponds, so when the volume is browsed, they are selected quickly and surely the words to know.
