Awfull Stuff ! Stick To Plywood or good solid - you won't regret it !

I've used chip and particle board successfully in my shelving system. Since 
it is either in compression or forced to bend in a complex shape, it seems 
quite stable. Few fasteners are used and the dado cut prevents the separator 
boards from splitting. However the thickness should be about 50% more than that of 
plywood for the same stability and that removes any cost advantage. And it is 
very heavy.

Conventional shelving made with particle board in the museum library is a 
disaster. It had to be propped up in several ways. It also is sensitive to 
moisture and humidity changes causing real problems if the bookcase design requires 
tight dimensions. I don't know if the formaldehyde outgassing problems have 
been solved, though there is some of that with plywood too.
