Summerhill School: A New View of Childhood in 1993. Its contents are a repackaged collection from four of Neill’s previous works. The foreword was written by psychoanalyst Erich Fromm, who distinguished between authoritarian coercion and Summerhill. The seven chapters of the book cover the origins and implementation of the school, and other topics in childrearing.
