1. Colophon

Our look is the result of reader comments, our own experimentation, and feedback from distribution channels. Distinctive covers complement our distinctive approach to technical topics, breathing personality and life into potentially dry subjects. The animal on the cover of Java Network Programming, Second Edition, is a North American river otter (Lutra canadensis). These small carnivores are found in all major waterways of the United States and Canada, in almost every habitat except the tundra and the hot, dry regions of the southwestern U.S. They weigh about 20 pounds and are approximately two and a half feet long, and females tend to be about a third smaller than males. Their diet consists mainly of aquatic animals like fish and frogs, but since they spend about two-thirds of their time on land, they also eat the occasional bird or rodent. Two layers of fur—a coarse outer coat and a thick, dense inner coat—protect a river otter from the cold, and, in fact, they seem to enjoy playing in snow and ice. A diving river otter's pulse rate slows to only 20 beats per minute from its normal 170, conserving oxygen and allowing the otter to stay underwater longer. These animals are sociable and domesticated easily, and in Europe, a related species was once trained to catch fish for people to eat. Beverly Goldfarb was the copyeditor for Java Network Programming, Second Edition. Deborah English was the proofreader. Jeffrey Holcomb, Sarah Jane Shangraw, and Claire Cloutier performed quality control reviews. Nancy Crumpton wrote the index. Interior composition was done by Claire Cloutier, Sarah Jane Shangraw, Molly Shangraw, and Joan McGaw.

The image on the cover of this book is a river otter. The cover was designed by Emma Colby using a series design by Edie Freeman. The cover image is a 19th-century engraving from the Dover Pictorial Archive. Emma Colby produced the cover layout with QuarkXPress 4.1 using Adobe's ITC Garamond font. Alicia Cech and David Futato designed the interior layout. The text was produced in FrameMaker 5.5.6 using a template implemented by Mike Sierra. The heading font is Bodoni BT; the text font is New Baskerville. The illustrations that appear in the book were created in Macromedia Freehand 8 and Adobe Photoshop 5 by Robert Romano and Rhon Porter. This colophon was written by Leanne Soylemez.

Whenever possible, our books use a durable and flexible lay-flat binding. If the page count exceeds the lay-flat binding limit, perfect binding is used.
