Abstract: A shelf label system for organization of products according to a modular plan identifies product information on a retail store shelf. It retains original location and product information. The system comprises at least one elongated shelf label track attached to a front face of the retail store shelf, a plurality of label holders, each fitting within and able to move along a length of the shelf label track. Each label holder has a hinged panel that can be folded such that only a first face of the hinged panel is visible. In an open position, a face of the main panel and a second face of the hinged panel are visible. In an alternative embodiment, the label holders are allowed to move along the slot but can only flip over in the cutouts. A locking cover may be implemented to prevent unauthorized persons from modifying the labels.
