An indexing system for a book, the system comprising an enclosure for the book, the enclosure having a back wall and a top wall capable of pivoting relative to the back wall. The top wall carries a scale with a displaceable slide and the scale carries indications that correspond to specific pages in the book. The system also includes plurality of book tabs adapted to be attached to specific pages of the book. The slide is attached to at least one arm that includes a lug adapted to engage a tab. Actuation means cause the lug to move from a disengaged to an engaged position in which the lug engages the tab, whereby displacement of the slide to a selected page causes the arm and lug to be positioned adjacent a selected tab and activation of the actuation means causes the lug to assume the engaged position with the selected tab so that when the top wall is pivoted open the book is opened at the selected page.
