What can you say about a classic? Dudley’s number theory text was first published in 1969; this volume is a faithful reprint of the second edition, from 1978. The writing style is engaging and at a level which makes this book accessible to a wide audience. There are 23 chapters that offer a variety of choices for coverage. The selection of exercises is excellent. There are enough “easy” problems so as not to discourage a student, but also enough that challenge as well. A perfect balance!

Even if you choose not to use Dudley’s book as the required text, its availability in paperback makes it an excellent resource available to everyone.


Herbert Kasube is Professor of Mathematics at Bradley University in Peoria, IL.
