Paul Erdos liked to talk about The Book，in which God maintainsthe perfect proofs for mathematical theorems， following the dictumof G. H. Hardy that there is no permanent place for uglymathematics. Erdos also said that you need not believe in God but，as a mathematician， you should believe in The Book. A few yearsago， we suggested to lum to write up a first （and very modest）approximation to The Book. He was enthusiastic about the idea and，characteristically， went to work immediately， filling page afterpage with his suggestions. Our book was supposed to appear in March1998 as a present to Erdos’ 85th birthday. With Paul’s unfortunatedeath in the summer of 1996， he is not listed as a co-author.Instead this book is dedicated to his memory.
