Our Comments:
We have discovered a printing problem with this book. After page 476 (where page 477 should be), one finds page 487, then page 478, 479, 480, etc, etc. In other words, page 477 is missing and has been replaced with page 487.

After informing the publisher of the above-mentioned printing problem, they have responded by stating that they and the author are already aware of this issue. Rather than recall and/or reprint the book, they have decided to simply put an "errata" page on the author's site:

All copies "out there" have this problem. We have copied the errata page from the author's site and inserted it into our copies of the book.
