Some discussion of psycho-analytic developments appears in both these volumes in the chapters on Psychotherapy, together with sections on group psychotherapy, research and training, and psycho-therapy in schizophrenia. In neither volume is a systematic survey of psycho-analytic work attempted, although Nevitt Sanford's contribution to Volume 4 underlines some important recent developments It is likely that these reviews will be of more use to psycho-analysts for the bird's-eye view they give of development in other and increasingly specialized areas of psychology.
