New Law and Ethics in Mental Health Advance Directives (Penelope Weller) looks like an interesting book for those working with psychiatric advance directives.
Scientology material might be interesting too (CCHR).
Research papers and Internet contains lots of misleading information. Some psychiatric “research” is in a state of “psychosis” (clozaril is claimed to be safer drug than seroquel etc).
