Abstract: A pair ofcylindrical rolls carried by a pair of wire arms having a spring connection to urge the rolls against one another. The rolls are offset from each other so that a book placed between the rolls can be held at a slanting upright position. As a modification, one of the rolls has a center groove to accommodate the protruding back seam of a book; in another modification, the rolls have locking grooves to prevent rotation of the rolls. In yet another embodiment, one edge portion of each of the rolls is bevelled to permit the device to be positioned in a slanting position. In further embodiments, auxiliary supporting members are mounted to one of the rolls.
