Jed, according to the back matter in the book, the exhibit will be at the Etherton Gallery in Tuscon until January 8, 2017 (it started there November 8), then moves to the McDonough Gallery of Art, Youngstown State University, Ohio, from January 20 through March 3, 2017.
If you are interested in purchasing the book, it is available on Amazon. If you would like a copy autographed by Alex Webb, you may still be able to purchase a copy from the store at Magnum Photo:
https://shop.magnumphotos.comTheir website says its still in stock, autographed. Their price is $75 (as compared to $60 retail, unsigned, or $55.27 at Amazon).
An alternative Alex Webb title is
The Suffering of Light, which currently is only $45.09 at Amazon (compared to $65.00 retail, unsigned). Both titles are great books, but
The Suffering of Light not only covers Webb's work over a period of years, it covers a broader geographic range as well. It is a larger book, and contains some of Webb's most iconic work.
Finally, if you have not done so already, I urge you to check out the work of fellow LVL member Allen Bourgeois. His work is terrific, and he is an admirer of Webb's work. You can see Allen's work on this website, listed under
