ABSTRACT:
In a marking apparatus and method for books, double sided tabs have adhesive so that the tabs may be adhered to pages of books, with a number-bearing portion of the tab extending from the page. Adhesive occupies one-half of one side of the tab, and numbers are written in opposite directions on opposite sides of the tab so that the tab may be affixed to a left or right page of a book to clearly mark the page and the point on the page to which it refers. Learning key cards have numbers corresponding to the tabs. Brief notes are written on the lines, and the cards are attached to the front leaf of a book. The tabs are attached directly to the learning key, or they are attached on the inside of a cover or opposite leaf of the book. An envelope or jacket-type holder is adhesive-backed for fastening to an inside of the book, and the tabs are mounted on a release coating on the outside of the envelope-pocket. Learning key cards, each with individual numbers corresponding to the tabs, are inserted in the pocket so that an entire card is available for notes in reference to the corresponding tab.
