An adjustable book support, eg a means of restraining books on a shelf, has a book engaging frame 14 with an integral shaped head to enable it to slide along an angle track 11. The frame, when tilted, can slide along the track but when positioned vertically remains locked into position. Integral guards 13 prevent any disengagement of the heads 10A and 10B from the angle track 11, fixed by flange 21 to the underside or to the face of a shelf. |
