Typically built from sets of encyclopedias over a framework of recycled wood, these freestanding cases may be filled with books. They are as strong as any wooden case. Shelves maybe fixed at any height, not adjustable. All are built to order so that the color and dimensions suit your room. Prices range from $900-2,000 depending on size. Discounts are offered when you supply the books. Shipping costs vary with size and distance.
