A method and apparatus for moving book shelf units is disclosed. The book shelf units to be moved are of the type having vertical standards generally perpendicular to the ground and having a plurality of vertically spaced slots for supporting horizontal shelves between the standards. The vertical standards of the book shelf units are retainably engaged at positions therealong spaced from the ground. Moving devices are operatively connected to the engaging devices for cooperatively moving the engaging devices in a generally vertical manner relative to the ground. Therefore, movement of the engaging devices when retainably engaged to the vertical book shelf standards lifts and lowers the book shelf. Rolling devices are connected to the moving devices which enable the apparatus to be moved across the ground thereby moving the book shelf unit.
