The uppermost page of an opened volume is rubbed toward the volume's spine to buckle the uppermost page and permit air to enter a space between the buckled page and the next page. The buckled page is then released to fall back toward its initial position and form an air layer between the uppermost page and the next page. The uppermost page is attracted upward by applying a suction force and a plate is moved along a path crossing the attracted uppermost page to turn it.
