This book represents the hard work of a number of talented individuals to whom I owe a great many thanks. For starters I want to thank Emi Smith, who as acquisitions editor, helped make this book a reality. I especially need to express my gratitude to Jenny Davidson, who served as this book’s project editor. As she has demonstrated so many times in the past, Jenny’s guidance and editorial skills were essential to the success of this book. Thanks also go out to this book’s technical editor, JT Hiquet, for providing invaluable insights and technical advice and to Sandy Doell, who served as the book’s copyeditor. Lastly, I’d be remiss if I did not remember to thank all the people working behind the scenes at Course Technology PTR for all their contributions and hard work.
