“Libraries, over the centuries, have been the most important way of keeping our collective wisdom. They were and still are a sort of universal brain where we can retrieve what we have forgotten and what we still do not know. If you will allow me to use such a metaphor, a library is the best possible imitation, by human beings, of a divine mind, where the whole universe is viewed and understood at the same time.”
