On November 6th, 1966 the Italian city of Florence experienced one of the worst flooding in its long history. The heart of the city disappeared under 3 meters of water. Two important libraries: the Biblioteca del Gabinetto Vieusseux and the Biblioteca Nazionale Centrale Firenze were affected. Over 1.5 million books from these libraries were damaged by the water. The only solution: put those precious books drying in a giant warehouse.
