Abstract: A spring loaded display device is described particularly suited for attachment to the leading edge of a shelf such as a bookshelf, the display unit including a clip mechanism for securely grasping the top and bottom surfaces of a shelf at its edge, the clip mechanism hingedly connected to a display unit which can freely rotate about the hinged connection. The display unit itself, generally of rectangular configuration, is designed to receive a document, and includes a transparent face so that the document contents may be easily viewed.
