Each chapter written and edited by experts in their field. Click a chapter at the left to learn more about what is covered (just the facts) and what is left out (the fluff). Small parts from throughout the chapter are included.

• A quick, handy reference. More efficient than Google, and available even when the internet is not. Flip right to the chapter and find your answer in minutes.

• A review for technologies once mastered but since forgotten. Remember when you built that JSP application 2 years and 7 projects ago? Here's a refresher.

• A summary of a language you're not familiar with. If you're a Java programmer, check out the C# chapter and get up to speed. If you're a web developer, read through the database chapters. If you're a Unix admin, brush up on dynamic web content. Learn COBOL!
