An improved corner guard that consisting of a guard body with an adhesive bottom surface layer, a pair of orthogonal fold lines designed to align with a pair of corner edges, a pair of fixed edge tab portions extending inwardly from the fold lines, and a central portion extending between the fixed edge tab portions. The central portion extends either beyond or inwardly from an imaginary linear line interconnecting the terminal ends of the fixed edge tab portions, thus effectively preventing the book cover's corner from creasing along the linear interconnecting line. Both the fixed edge tab portions and the central portion of the guard may additionally include one or more curvilinear portions to prevent objects from catching or tearing on the corner guard. Additionally, the guard also preferably includes a pair of fold-over tabs extending outwardly from the fold lines. The tabs may be designed to fold over the corner edges and adhere to a back surface of the corner, they may be designed to be permanently positioned at right angles to the body for alignment of the guard with the book, or they may be designed to be torn off once the guard is aligned with the corner of the book. When the fold-over tabs are positioned permanently at right angles to the body, they include means for biasing the book cover in a flat and closed position, as well as one or more apertures for accepting and retaining a bookmark leash, rubber band or the like.
