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
DIY "Floating Bookshelf" Add two tiny nails just under the brackets. Open the bottom book, and used the nail to hold the cover closed. This hides the bracket completely, making the bookshelf invisible.
