I intend to make the PDF available to my extended family, and friends who are interested in the subject which is primarily prehistoric archaeology of the Fertile Crescent, Steppes, Iran, the Stans, and Indus Valley. I write novels set in those places and times. The novels as inspired by rapid advances in dating skeletons and breakthroughs in the Steppes. 234 Megabytes is a little big and the topic too esoteric for most.
