Abstract: A telephone book holder is described which consists of a spine with two groups of parallel channels in its rear surface. Edges of front and rear covers are dimensioned to be slid into respective channels of each group, the edges being connected to the covers by living hinges. Book retaining wires are pivotally connected at the top end of the spine and can be press fitted to the other end to retain a telephone book in position. Top and bottom caps are securable to the ends of the spine to retain the covers and the wires on the spine. The covers can be replaced without requiring removal of the book or complete detachment of the end caps and the thickness of the book to be held is adjustable by sliding the covers into appropriate channels.
