When google and resource/stock websites fail, this book succeeds.
I find myself turning back to this book over and over because there are decent references for difficult parts to draw such as the hands and feet. What I also like is that everything about this book is realism so the anatomy is accurate, not exaggerated. It also shows some differences between male and female anatomy (like the bone structures of the hips, skull, fat distribution, etc, etc). In section of the book, it also gives short details on historical artistic anatomy. Though that section may not be useful to some, there's at least a section on each of the body part areas except for the genitalia. There's even a few sections dedicated to form and body movement.
Overall, this book is worth picking up, especially considering how cheap it is for the valuable information.
P.S. There is artistic nude, so I don't think children should be using this book...
