The designers of the Hofbibliothek and the Biblioteca Casanatense in Rome played games with perspective and the perception of height. The library at Melk Abbey is another example. Fixed in position, the shelves there are placed to enhance the sensation of scale. The higher shelves are set closer together, and the very top shelf is so impossibly shallow that real books will not fit. For that shelf, the designers resorted to fake books: little book-shaped blocks made from wood and labeled with playfully literal titles such as Wood by Anonymous and Empty by Woody.
