This page provides errata for the fourth edition only. Please see the third edition errata page for the previous edition.

The errata submissions have been approved and validated by the authors.

An edition and a printing are different things. There will be multiple printings of this latest (4th) edition.

You have the fourth edition if the cover looks like the image on the left side of this page. To determine which printing of the fourth edition you have, look at page iv, which is the copyright page just before the Table of Contents. There will be one line containing a sequence of numbers counting down. The last number on that line is the printing number.
