      Acknowledgments

      A tremendous amount of work went into bringing this book to the bookshelf, and all that work wasn’t done by me alone. Several factors combined to make the review process and the final production of this book a challenge.

      First and foremost, I would like to thank John West, my editor and friend, who was amazingly patient and calm, even when there were technical challenges to overcome.

      Next, we enlisted the help of more reviewers than usual. Four of these reviewers read the book from cover to cover and made excellent suggestions for improvements and found some subtle and obscure errors. So, kudos to Gerry Hobbs, Catherine Truxillo, Jeff Smith, and Marc Huber.

      Other reviewers read chapters, particularly those where they had a particular expertise. Sincere thanks to Rob Agnelli, Paul Grant, Sanjay Matange, David Schlotzhauer, Jim Seabolt, and Sue Walsh.

      Since the decision was made to use HTML output instead of simple list output, considerable extra effort was required. The production team needed to “touch” approximately 161 image files so that they would look good both in print as well as on the various eBook devices. The people involved in this process were: Jennifer Dilley, designer; Candy Farrell, technical publishing specialist; Joan Celmer, copyeditor; and Mary Beth Steinbach, managing editor.

      No book would be successful without having people to market it. Thanks to Aimee Rodriguez and Stacey Hamilton for this essential task.

      Finally, I salute the artists who created the front and back covers of the book. Nice job Jennifer Dilley and Marchellina Waugh.
