Don't stack collections. Shelves are excellent for items stored in boxes. Solid boxes can be stacked. See our information on Boxes . Covering Shelves Dust and light damage can occur to items stored on shelves.
Many museums attach covers to the shelving.
Clear polyethylene sheeting, cotton sheets or washed muslin are common. Polyethylene is see-through and water resistant, but attracts dust and does not filter light. Muslin or cotton sheeting is lighter, cheaper, provides light protection and can be washed when it gets dirty. It does not protect from water leaks. Methods of attaching dust covers vary.
