Hi Norman,
If you are writing a review, then I assume that you have read Dr. Gilligan's books:
"Therapeutic Trances,"
"The Courage to Love,"
The Legacy of Milton H. Erickson Selected Papers of Milton Erickson and/or Therapeutic Conversations."
Most of the books on Ericksonian Therapy, edited by Jeff Zeig, have articles written by Dr. Gilligan. Ericksonian Monograph Number 7, edited by Stephen Lankton has an article.
On the Milton H. Erickson Foundation website is a review of "The Courage to Love. I did not look at past issues of the newsletter, but I would not be surprised if there are other reviews. I would look on his website to see if there are any leads on what you are looking for.
I hope this helps.
Best wishes,
Joe O'Rourke
