The update is 7 pages. I'm curious as to why Mr. Young didn't just update the original, forward to Amazon.Com so we could download the corrected book as opposed to having to add a note then finding the update. Amazon allows downloading previous purchases at no cost. I added a note to that section on my Kindle and Kindle for PC but only a note on where the update is on my PC. We surely can't add 7 pages of info.
