"The world of books is the most remarkable creation of man. Nothing else that he builds ever lasts. Monuments fall, nations perish, civilizations grow old and die out, and, after an era of darkness, new races build others. But in the world of books are volumes that have seen this happen again and again, and yet live on, still young, still fresh as the day they were written, still telling men's hearts of the hearts of men centuries dead." - Clarence Day Jr.
