My works published elsewhere are covered by commercial copyright as indicated in the embodiments of those works.
I intend that for all works I shall retain copyright, but the works may be reproduced freely, provided (a) there is no material charge for the reproduction except a small fee to cover (without profit) the cost of the reproducing; and (b) the work is disseminated so that there is no subsequent restriction of free reproduction. Basically, copying (but not modification) is okay, but you can’t make money off it or help anyone else to make money. If you have questions,
ask.
