Resource Guide

I am working on the resource list for Bill P's new book, listing books,
articles, videos, demonstrations etc.

How about Web sites? I have not checked out all the web sites relating to
PCT. Would it make sense to list Rick Marken's, Bill Powers', Ed Ford's
Respthink, Gary Cziko's CSG site. What web sites should be considered?

Will appreciate comments and suggestions.

Best, Dag
