Sad though it is to have two major Australian bricks'n'mortar bookshop chains closing (Angus & Robertson and Borders), I noted the other day at the store nearest me that they are selling off a lot of shopfittings, including perspex book holders, wire folding book holders, storage cubes and slatwall, that could be useful for libraries.
I got some perspex book holders (five linked units) for $10. The wooden storage cubes were $40, the slatwall $100 for a large section (which would suit the end of a shelving run, for example). Little hinged wire bookstands $2.
