Abstract: A clip-on bookmark for finding a place in a book is disclosed wherein a substantially planar book marking member has two opposed covers with at least one edge portion with indicia, such as advertising message, associated with at least a portion of the covers. A slot is formed by the marking member along the edge portion and means for removably fastening the marking member to the book is received by the slot. The indicia may be imprinted directly onto the covers or may be contained on an item for receiving the indicia which is laminated to the covers, which may be of transparent, semi-rigid material, such as vinyl plastic. The covers may also form a pocket for removably holding a card on which the indicia is contained. The fastening member comprises oppositely positioned first and second legs joined at a reverse bend and form an open side opposite the reverse bend. The first leg is mounted in the slot and the second leg is positioned outside the marking member.
