What's in the Book? To get an idea you can look at the Table of Contents and the Preface.
Printed Version: The book was published by Cambridge University Press in 2002 in both paperback and hardback editions, but only the paperback version is currently available (ISBN 0-521-79540-0). I have tried very hard to keep the price of the paperback version as low as possible, but it is gradually creeping upward after starting at $30 in 2002. Less expensive printings have been made for sale in China (Tsinghua University Press) and South Asia. A Russian translation was published in 2011.
Electronic Version: By special arrangement with the publisher, an online version will continue to be available for free download here, subject to the terms in the copyright notice. There are two different formats available:
Note: Section 3.2 has been revised from the original version, necessitating a renumbering of items 3.11-3.21. Similarly, pages 352-355 in section 4.1 have been revised, with renumbering of items 4.13-4.17.
Corrections: I am trying to keep an up-to-date list of corrections for all the errors, typographical and otherwise, that I am aware of. There are two lists:
My sincere thanks to all the people who have sent me corrections.
The electronic version of the book is kept up to date to include the corrections as they come to light. It also contains a few small revisions that I couldn't resist making. None of these corrections and revisions involve renumbering of pages, theorems, or exercises, except as noted above for sections 3.2 and 4.1.
Revisions and Additions: At some future date there may be a more extensively revised edition incorporating various improvements that are posted on the Revisions and Additions page. Also available are some additional exercises.
The Exercises: I have not written up solutions to the exercises. The main reason for this is that the book is used as a textbook at a number of universities where the problem sets count for part of a student's grade.
Typography: Some comments on how the book
was made to look the way it does can be found here.
