Using Drupal: A great start to web content
USING DRUPAL by Jeff Robbins, Angela Byron, Addison Berry, Jeff Eaton, Nate Haug, James Walker.
That is a long list of names for one book! Even so, if you are considering using the Drupal Framework, this book will get you well grounded in the basics.
Drupal6 is powerful and versatile. Popular wisdom is that if the stock Drupal download lacks something you need, there is usually a module to fulfill that need. This book teaches you about the right modules to use make a Job Posting Board for a hypothetical University, a Product Review Page with a rating system, a Wiki, and many other project oriented gems. The book steps you through the Ubercart eCommerce modules in setting up an online store. Suffice to say Using Drupal shows you a wealth of features and abilities without the need to understand programming languages.
Even a PHP Programmer who intends to use Drupal should read this book to get up and running with this framework. I would say this is a must-have book.
