Review of the hardback: 'This is a wonderful book in memory of Paul Erdos. There is also a long introductory paper by Miklos Simonovits and Vera T. Sos about Paul Erdos. This paper is particularly well written and gives a very good idea about what kind of man and what kind of mathematician Paul Erdos really was. Without any doubt, these papers belong to the private library of any mathematician in combinatorics.' Bulletin of the Belgian Mathematical Society Review of the hardback: 'This book can be recommended to all those interested in combinatorics and cognate fields.' Niew Archief voor Wiskunde
