Some pretty awesome book shelves. I personally want floor to ceiling shelves covering at least two walls in my spare bedroom. until I upgrade from condo to a house with a full-blown library / reading-n-nook room :D
The most innovative book arrangement: Cool DIY pipe book shelf.for the industrial looking living room.all parts can be bought at home depot, and they will even thread the pipe for you there to the length that you need it! Maybe for bedroom idea.
