Sybil

Sybil is a 1973 book by Flora Rheta Schreiber about the treatment of Sybil Dorsett (a pseudonym for Shirley Ardell Mason) for dissociative identity disorder (then referred to as multiple personality disorder) by her psychoanalyst, Cornelia B. Wilbur. The book was made into two television movies of the same name, once in 1976 and again in 2007. There have also been books published after the fact, challenging the facts of Sybil's therapy sessions. A few examples of these are SYBIL in her own words, Sybil Exposed, and After Sybil.
