The library is not a shrine for the worship of books. It is not a temple where literary incense must be burned or where one's devotion to the bound book is expressed in ritual. A library, to modify the famous metaphor of Socrates, should be the delivery room for the birth of ideas - a place where history comes to life.
Just as there is no loss of basic energy in the universe, so no thought or action is without its effects, present or ultimate, seen or unseen, felt or unfelt.
