:: Well, I think "and its related organizations" definitely includes the Scientology Publications company who published "Creative Learning", and authors like Minshull and Frater who Hubbard specifically licensed and authorized. Minshull's books were even sold thru Orgs in the 70s. I don't know anything about Gilham, Braddeson and Sharpe's books, but the list was meant to be all-inclusive for Scn-related publications that were at least at one time sanctioned by Hubbard or the Church (while disincluding books about Scientology by non-Scientologists, and unauthorized squirreling publications by Freezoners).
