" There, I said to myself, are the reasons for the silence and darkness that surround the library: it is the preserve of learning but can maintain this learning unsullied only if it prevents its reaching anyone at all, even the monks themselves. Learning is not like a coin, which remains whole even through the most infamous transactions; it is, rather, like a very handsome dress, which is worn out through use and ostentation. Is not a book like that, in fact? "

― Umberto Eco , The Name of the Rose
