 In 1996 Basic Books published the "Textbook of Transpersonal psychiatry and psychology", marking the first comprehensive textbook introduction to the field.As noted by Liff, the book does not differentiate clearly between the two areas of transpersonal psychiatry and transpersonal psychology.However, in the August 1999 issue of Psychiatric Annals a distinction was made, and special attention was paid to the area of transpersonal psychiatry.
