in here that you can't get for free on the Web, then, no. There is not. In fact, there is little information in any Java or Linux book that is not available for free on the Internet. In fact, in each of our chapters we will tell you where on the Web to find virtually all of the information we present, and then some. And yet books continue to sell, and we have the chutzpah to ask you to buy the book. The reason is that Web information is scattered, unorganized, and of highly variable quality. We will be trying to bring all the relevant information together in this book, in a clearly organized manner (and, we would like to believe, at an acceptably high level of quality). We think that has value. Also, this book is part of the Bruce Perens' Open Source Series. This book is part of the Web literature. And you may freely read it and use it on the Web. We hope this book will be one of those you use on the Web and buy on paper. We don't know about you, but we like to use Web books for reference, but for reading, we like books. We own at least three books that are available for free on the Web: Thinking in C++, Thinking in Java, and O'Reilly's Docbook: The Definitive Guide. We hope that open publishing will be the new model.
