This huge book contains 643 entries, a 1,500 title bibliography and a 6,000 item index. It is a tremendous collection of definitions, explanations, and discussions. Although it will not suffice for the student in psychoanalytic training it is a good reference for students and practitioners of psychiatry. Eidelberg's prologue is a well meaning but a somewhat out of place plea for greater liberality and democratization of the psychoanalytic "Establishment." This is a worth while addition to psychiatric libraries.
