Abstract: A shelving system for parallel sloping shelves in which each shelf is of greater depth than the shelf above it, and having transparent divider units located in pairs on the shelves. Each divider unit has a longitudinal upright divider member extending over a substantial portion of the depth of, and at least 75 percent of the height of, its shelf; a slide member extending the full length of the divider member and connected to the bottom of the divider member and extending at right angles thereto; and a stop member of the same height as the divider member. The stop member is connected to the front edges of the divider and slide members and extends at right angles to each. The pairs of divider units on the shelves have their stop members facing each other but with a gap therebetween, so that a shelf user can insert his hand through the gap to lift an article from or replace an article on the shelves.
