“Never lend books, for no one ever returns them; the only books I have in my library are books that other folks have lent me.”

“We have never heard the devil's side of the story, God wrote all the book.”

“I awaited Signor Polizzi's reply with ill-contained impatience. I could not even remain quiet; I would make sudden nervous gestures - open books and violent close them again. One day I happened to upset a book with my elbow - a volume of Moréri. Hamilcar, who was washing himself, suddenly stopped, and looked angrily at me, with his paw over his ear. Was this the tumultuous existence he must expect under my roof? Had there not been a tacit understanding between us that we should live a peaceful life? I had broken the covenant.”

“This book bore the label R>3214 VIII/2. And this painful truth was suddenly borne in upon the mind of Monsieur Sariette: to wit, that the most scientific system of numbering will not help to find a book if the book is no longer in its place.”

“I have always preferred the folly of the passions to the wisdom of indifference. But just because my own passions are not of that sort which burst out with violence to devastate and kill, the common mind is not aware of their existence. Nevertheless, I am greatly moved by them at times, and it has more than once been my fate to lose my sleep for the sake of a few pages written by some forgotten monk or printed by some humble apprentice of Peter Schöffer. And if these fierce enthusiasms are slowly being quenched in me, it is only because I am being slowly quenched myself. Our passions are ourselves. My old books are Me. I am just as old and thumb-worn as they are.”

“The books that everybody admires are those that nobody reads.”

“People who have no weaknesses are terrible; there is no way of taking advantage of them.”
