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 Cisco IOS Access Lists is a burro. "Burro" is, more or less, just another word for donkey, but it is also used specifically to mean a type of small feral donkey found in the southwestern United States and in Mexico.

Donkeys (Equus asinus) are descended from the African wild ass. They stand three to five feet tall at the shoulder, have a short mane, tufted tail, and big ears, and live for about 25 years. They were domesticated over 5,000 years ago, and they are still often used as pack animals, due to their surefootedness on rough terrain. Donkeys can be mated with horses, but the offspring of these matings are usually sterile. A female donkey (called a jennet or jinny) mated with a male horse produces an animal called a hinny. The offspring of a male donkey (jackass) and a female horse is a mule.

The feral burros of the southwestern U.S. and Mexico are the descendants of escaped and freed pack animals. Some believe the large feral burro population is driving desert bighorn sheep into extinction, by competing with them-successfully, it would seem-for scarce desert resources. Emily Quill was the production editor, Matt Hutchinson was the copyeditor, and Mary Anne Weeks Mayo was the proofreader for Cisco IOS Access Lists. Colleen Gorman and Catherine Morris performed quality control reviews, and Edith Shapiro provided production assistance. Lucie Haskins wrote the index.

Ellie Volckhausen designed the cover of this book, based on a series design by Edie Freedman. The cover image is a 19th-century engraving from Old-Fashioned Animal Cuts. Emma Colby produced the cover layout with QuarkXPress 4.1 using Adobe's ITC Garamond font.

Melanie Wang designed the interior layout based on a series design by Nancy Priest. Anne-Marie Vaduva converted the files from Microsoft Word to FrameMaker 5.5.6 using tools created by Mike Sierra. The text and heading fonts are ITC Garamond Light and Garamond Book; the code font is Constant Willison. The illustrations that appear in the book were produced by Robert Romano and Jessamyn Read using Macromedia FreeHand 9 and Adobe Photoshop 6. This colophon was written by Leanne Soylemez.
