I checked through my "sent" emails and found the string of emails from when I ordered the guide the last time. The wife of one of the gentlemen that put the guide together said that her husband had died several years earlier and that since orders had dropped off significantly they would no longer publish the guide. She recommended at that time that she would honor orders through December of 2017. I sent an email yesterday asking if any copies of the guide might still be available either in print or as a downloadable PDF file, but have yet to hear back from her. I'll try again and let you know what I find.
