Drupal 7 Bible
New to Drupal? Ric Shreves and Brice Dunwoodie’s Drupal 7 Bible is a perfect starting guide. From the painless installation process to all the core features to customizations, Shreves and Dunwoodie make Drupal seems less intimidating than it appears to be. By using Drupal, one can set up a solid, powerful content management system without touching the codes.
I am fairly new to Drupal simply because most of the work I have done could be accomplished using WordPress. While both WordPress and Drupal are content management systems, they serve different purposes. The choice to implement one over the other is up to the web designers and developers, but to have both for us to use for free is a huge advantage.
