All,
After lurking on the board for several months, I thought I might be able to make a post that would be of some help to you guys. Cottle's book is out of print, and he now works for thinkorswim.com (an online brokerage). His new company has bought the rights to the old book. He recently introduced an updated version of the book, titled "Coulda, shoulda, woulda". This book is available for free at the Online Trading Expo, if you go to his talk. Please let me know if you have any questions.
