For those who have heard of the Kelly mythos and want to explore the science behind it, this book will be an instant classic. The editors have collected all the pivotal original papers, spanning centuries and the rarely bridged gulf between theory and practice. This book is indispensable for anyone interested in Kelly's legacy. -- William Poundstone ""Author of ""Fortune's Formula: The Untold Story of the Scientific Betting System That Beat the Casinos and Wall Street"""" The present handbook assembles in an impressive way the classical papers and also provides the link to modern research. It also presents important papers with a critical view towards the Kelly criterion. Among them figures the famous three-page paper of P. Samuelson from 1979 which is written by using exclusively one-syllable words. -- Professor Walter Schachermayer ""Faculty of Mathematics, University of Vienna""
