Libraries are sanctuaries from the world and command centers into it . . . They are, ideally, places where nothing happens and where everything that has happened is stored up to be remembered and relived, the place where the world is folded up into boxes of paper. Every book is a door that opens onto another world . . . and a library is a Milky Way of worlds. . . . all imaginative, engrossing books are landscapes into which readers vanish.
