Query: Good information source

I am frequently disappointed with yoga books--but this book, upon first review, keeps me interested as there is a good deal of new information here. The illustrations (photographs) are abundant and helpful. Although I have not had the chance yet to begin the practice, I look forward to learning much from this book. I WAS disappointed, however, that it did not address asanas for migraines, as the publisher's description promised. This aside, I think there's alot of good information in this book and it seems well worth the price.
