Connectors are provided at two opposite ends of the cover material for connecting opposing sides of the cover material to one another to form sleeve-like configurations with the cover material adjacent the opposite ends which respectively receive the front and rear covers of the book in telescoping relationship. The portion of the cover material intermediate the opposite ends which are telescoped over the book covers is folded back and extends over the front and rear book covers and the book binding. A plurality of strips of material encircle each of the book covers to secure the portion of the cover material which is folded back and extends over the front and rear covers of the book to the adjacent covers.
