Abstract: Book coverings for protecting and improving the aesthetic appearance of books of varying sizes in which an outer wrapping sheet, which may be opaque or transparent, is cut or folded to conform to the height of the book leaving end flaps for the front and rear covers, and wherein generally elongated leaflets are provided to be cut to a dimension slightly greater than the height of the book for attachment to the outer surface of the front and back cover portions of the wrapper adjacent the end flap to form a loop on the inside of the book cover, the end flap being tucked under the loop to form a finished cover. The leaflets may be opaque or transparent and may be trapezoidal in shape or rectangular. The covers are positively held by the loops on the books without direct attachment thereto.
