Hi Loren, I understand that the book: "Behavioral Vision: A Multi-Sensory Approach to Processing Information & Learning" by Robert C. Pepper is currently out-of-print.  It no longer seems to be available through the Optometric Extension Program.  I have thoroughly searched the web-site that you provided (oep.org) and I was not able to track down a copy of Pepper's book.  Further, I have tried in vain to locate a copy via amazon.com, bookfinder.com, alibris.com, ebay.com, barnesandnoble.com and abebooks.com.  I have sent out an e-mail to the publisher and am awaiting a response.  In the meantime, would you be willing to provide the direct link to the specific location within oep.org where I might find this book advertised? Happily Hunting, Pete
