This book was created as a collaborative project hosted at http://books.mozdev.org. The authors of the book have become aware of the benefits of creating a project in an open source method while working within the Mozilla community and wanted to extend these benefits to the creation of the book itself.
The content of this book was released under the Open Publication License (OPL) and is available at the site mentioned in the previous paragraph and at http://www.oreilly.com/catalog/mozilla/. Anyone interested in contributing to the further development of this book is encouraged to visit the site; they can help us make sure that this book lives on as an active document that will continue to be useful to the Mozilla community.
The examples used throughout the book contain code fragments that were created specifically as examples to highlight the use of a particular aspect of Mozilla application development. Several existing Mozilla applications are also used as examples and more information about each is provided in the chapters where they are used. All numbered examples in the book can be found online at http://books.mozdev.org/examples/ and http://www.oreilly.com/catalog/mozilla/.
