‘Emma of Gor’ has written a useful guide for those wanting to take a very purist approach to making and playing their characters. You can find that link here:
More so than most games, ‘Tales of Gor’ cries out for players to create characters that seem a natural fit to the thriving and detailed world they live in. This is not really the campaign setting for you to foist a generic D&D adventurer on. To get the most out of the Gor setting you’d do well to consider the kind of people that live on the Counter Earth. While you don’t have to play ‘typical Goreans’ – the game after all makes the point many times that Gor is yours to interpret as you will – what follows is a guide to character creation if you want to truly capture the flavour of the kind of people who live, fight and lust throughout the Gorean cycle.
World of Gor, meanwhile, has been reviewed, link below.
In strict alphabetical order, the entries cover everything from prominent individuals to flora and fauna, popular beliefs and customs, and matters of everyday life. They are illustrated by relevant quotations from the books as well as splendid pen-and-ink drawings that capture the exotic feel of the world well. Even where slaves are involved, they remain tastefully done… and are particularly fascinating when they depict the exotic animals of Gor.

I see some books coming through on amazon.com. Have you checked the ability for them to come through on amazon.ca?
I’m afraid I don’t know whether they’ll come through on that. I’ll look into it.
