I love this idea for temporarily using your hardback books as shelves- as seen at Drink, Shop & Do in King's Cross.
The whole shop/ cafe/ project is a vintage lovers dream palace. You can buy everything in the shop from the chairs you sit on to the teacups the candles are lit in. You can take classes in making pearl necklaces or go to the dot to dot disco or just relax with a cup of tea/ cocktail and play a board game. HEAVEN.
