Ditto. I think the good thing about this site John Juedes' has is that he identifies himself. Also, Karl Kahler's book is full of information well documented.
Here's my two cents on this topic:
I found references to The Way simply by going to public and college libraries and looking through books about cults or new religions, etc. and checking the Index in each book. It is time consuming, but hey, if you want to dig, you gotta get out a shovel and put some elbow grease into it, as my dad used to say ...
One example was in a library in Amsterdam! Here's my blog post about finding Melton's book there: http://charleneedge....-library-treat/
Another one is a book from the AAR Studies in Religion 36 volume. The name is: Cults, Culture, and the Law: Perspectives on New Religious Movements. Published by Scholars Press, Chico, CA. 1985. Edited by Thomas Robbins, William C. Shepherd, and James McBride. The Way Int'l is cited on four different pages.
A word of caution about using quotes from this site. Most posters here use a fake name, so to outsiders, sometimes that detracts from the veracity of the stories here. In other words, they could be ghost stories. I don't have that attitude because I was in the group and can pretty much tell if something is bogus (but not all the time, I'm sure), but without an insider's knowledge, outsiders would not be able to sniff things out so well. Maybe ...
Good luck,
Charlene
