Requiring no more than a basic knowledge of abstract algebra this textbook presents the basics
of algebraic number theory in a straightforward down-to-earth manner. It thus avoids local
methods for example and presents proofs in a way that highlights key arguments. There are
several hundred exercises providing a wealth of both computational and theoretical practice
as well as appendices summarizing the necessary background in algebra. Now in a newly typeset
edition including a foreword by Barry Mazur this highly regarded textbook will continue to
provide lecturers and their students with an invaluable resource and a compelling gateway to a
beautiful subject. From the reviews: A thoroughly delightful introduction to algebraic number
theory - Ezra Brown in the Mathematical Reviews An excellent basis for an introductory graduate
course in algebraic number theory - Harold Edwards in the Bulletin of the American Mathematical
Society
