I read the design pattern book a long time ago and it was interesting, but it was more of an introduction to the topic. An experienced engineer can get the same content from Wikipedia, you’ll only miss the funny pictures and the "tutorial format." I could recommend the books to a beginner though especially at that price.

When I started, I preferred books like those ones because there was too many tutorials all over the place, and choosing was a bit confusing. I guess I would buy that if I was a beginner again.
