As we discover and fix errata, we list them here and our publisher puts them in a file so they can be corrected at the next printing of the book, and in subsequent editions. You can tell which printing you have by looking at the copyright page. Towards the bottom of the page, under the ISBN, there is a line of numbers, which looks something like this:

9 8 7 6 5 4 3 2 1

The rightmost number is the printing number. The example above indicates the first printing. Errata listed here may or may not be fixed in the book you hold in your hands, depending on what printing it is.
