All of our projects are copyright free. We distribute them for free, or else, where that is impossible, sell print versions for the costs of production and delivery alone. We've been doing this work continuously for fully three decades. If you want to help us expand the scope of our efforts, you can support our projects financially.
Since this is an all-volunteer project and we take no compensation for ourselves, we can make a little go a long way. If you have the means, consider making a one-time or recurring donation to us. Above all, though, the very best thing you can do for us and for the world is to put the information and skills we offer to use in your own efforts to change the world for the better.
See you on the other side.
