We have reported on this site a copy of the method of Haggart, sure that the text is not covered
by copyright or that his heirs can't claim the rights money.
The same agreement to create more informal copies was given of the same Haggart.
However, given that the purpose of the site is educational and cognitive (non-profit)
who believes the claim of copyright , contact me privately. Subsequently I will require an exchange
letters so that no one can draw an unfair advantage.
