This edition needs updating. I heard great things about the book and in general it helps the reader get to grips with some of the concepts of how Drupal differs from its competitors. However, it focuses on Drupal 6 mainly with a nod to Drupal 7. I installed Drupal 8 which is now the main version with Drupal 7 being supported. So many of the examples have been superseded and you have to do a lot of work to figure out how to do things. Plus many of the administration menus have changed drastically.
I would recommend that you not buy this edition but wait for an updated edition. The information is just too outdated to be helpful. I paid the full price and feel that I have been misled somewhat.
Having said that, as a guide for thinking about your projects and Drupal in general, as well as demonstrating some of the features with real examples, it is generally useful. But be prepared to do some extra work and to skip over some parts which are now ancient history or irrelevant.
