As a fly tier with many years of experience, I find this book helpful for getting ideas for new patterns, or recipes for patterns I don't tie enough to remember. However, if your looking for a "How To Tie Book" you'll want to start with something else. If you understand basic tying techniques, you should find this book helpful for recipes. Also, this book is kind of out dated, but not in a bad way. You'll find it easy to tweak the recipes to incorporate some of the newer materials available today. Or tie it as it was originally intended.
