by Bennett Cerf.Random House, $12.95. Cerf did not live to put the final polish on his memoirs, but that is no matter. His informal, anecdotal style is a suitable vehicle for the story he had to tell—that of a man who loved books, almost worshipped authors (provided they did not drink themselves into incapability), considered publishing a most honorable profession, and made a fortune by acting on these notions. He had fun and so will the reader. Illustrations.
