Title: INDEX TABBING SYSTEM ABSTRACT OF THE DISCLOSURE A method of making a book having index tabs in which the tabs are formed by inserts that are interspersed at appropriate locations with sheets for forming the pages of the book, during the book binding operation. Each insert comprises a six-page signature having first and second panels that are bound in with the sheets, and a third panel that carries the tab and is folded inwardly between the first two panels during the binding operation. After binding has been completed and the book has been trimmed, the panels that carry the tabs are folded out so that the tabs project from the trimmed outer edge of the book.
