Artistic Anatomy- Paul Richter (in French on a French website)

This book is a priceless tool.  I suggest buying it in English.  However, it is on this French website for free.

Pay attention to this, I do not care if you are learning how to draw, learning how to sculpt, or learning zbrush! If you are in a figurative art field, you need this resource.  Email if you have any questions or need help.
