Its a book of the proceedings of "The Fourth International Conference on Origami in Science, Mathematics, and Education (4OSME)" much like the past book on 3 OSME by Tom Hull. It was recently discussed on the O-List. I'll post Robert's reply:
"I have been horribly delinquent in pulling this together, but I am
spending most of my holidays on editing and formatting with the goal of
getting the MS ready to deliver in the next few weeks. (Contributors should
expect to receive edited versions of their articles shortly. Some already
have!)
Now, that probably means mid-spring at best for final MS readiness (it still
would have to go through the publisher's editing process), and so probably a
summer or fall publication date. The publisher has provided no publication
date (since I have provided no MS delivery date), so I don't know where
amazon gets their information. Perhaps wishful thinking. At any rate, it is
coming, but don't go sending them any checks just yet.
(And for the inevitable follow-up question; once I've gotten that MS off, I
will return my attentions to the next book, which will cover techniques for
designing geometric and mathematical single-sheet origami, including some
stuff on tessellations.)
(And speaking of tessellations, the pioneer of origami tessellations in the
US, Ron Resch, has been posting pix of his early work on his website,
http://www.ronresch.com. Definitely worth checking out.)"
