Whenever I use a technique I've learned about in a book, I try to make it a point that I'm doing that, and I frequently mention the book the technique comes from. Just because it's in a book doesn't disqualify it as an effective method. At the same time, being transparent about your methods is important, since the methods themselves should be subject to scrutiny and understanding.
