"When he was seventy-four years old the Cretan novelist Nikos Kazantzakis began a book. He called it Report to Greco... Kazantzakis thought of himself as a soldier reporting to his commanding officer on a mortal mission--his life. ... Well, there is only one Report to Greco, but no true book... was ever anything else than a report. ... A true book is a report upon the mystery of existence... it speaks of the world, of our life in the world. Everything we have in the books on which our libraries are founded--Euclid's figures, Leonardo's notes, Newton's explanations, Cervantes' myth, Sappho's broken songs, the vast surge of Homer--everything is a report of one kind or another and the sum of all of them together is our little knowledge of our world and of ourselves. Call a book Das Kapital or The Voyage of the Beagle or Theory of Relativity or Alice in Wonderland or Moby-Dick, it is still what Kazantzakis called his book--it is still a "report" upon the "mystery of things." But if this is what a book is... then a library is an extraordinary thing. ...
