Abstract: A combination book box/book rest which can be formed from a one-piece foldable blank is disclosed. The foldable blank may be made of cardboard or plastic and comprises a flat, rectangular central section with two lateral flaps hinged to the opposite sides thereof. Upper and lower flaps are hinged respectively to the upper and lower ends of the central section. The lateral edges of the upper and lower flaps releasably engage in grooves in the lateral flaps to form a book box. The end portions of the upper and lower flaps are also releasably engagable with each other to convert the blank into an inclined book rest support.
