Abstract
A device for retaining a book, such as a telephone directory, in a holder or on a flat surface, in order to prevent unauthorized removal or theft of the book. A plurality of pin-like retainer members are mounted in a pair of mounting members in laterally spaced, parallel relation. The number of retainers is determined by the thickness of the book. The pointed ends of the pin-like retainer members are shifted into the ends of the book and the assembly is secured either to the flat surface or to a support bar that is riveted or otherwise secured to the inner surface of the back of the holder. The pin-like retainers are frictionally retained either in a series of laterally spaced slots or bores in the mounting members so as not to be removable therefrom without the use of a tool and a substantial amount of force.
