An introduction to the theory of numbers. 4th ed. (English) Zbl 0086.25803
Oxford: At the Clarendon Press. xvi, 421 p. (1960).
Aus dem Vorwort der 4. Auflage: Apart from the provision of an index of names, the main changes in this edition are in the Notes at the end of each chapter. These have been revised to include references to results published since the third edition [(1954; Zbl 0058.03301)] went to press and to correct omissions. There are simpler proofs of Theorems 234, 352, and 357 and a new Theorem 272. The postscript to the third edition now takes it proper place as part of Chapter XX.
