Probably most important are a series of excellent biographical sketches of a whole variety of individuals who were important in the origin and development of psychoanalysis from the time of Freud to the present day. It is nice, for example, to find biographies of Baginsky, Brentano, Groddeck, and Herbart along with the usual crowd of pioneers and accepted experts in the field of psychoanalysis all covered in one volume. These biographical entries alone make the encyclopedia a worthwhile addition to one’s library. Curiously, although some relatively minor figures are included, biographies of some of the heavy hitters such as Loewald, Winnicott, Kristeva, and Kohut are not to be found. A related category of useful essays in the encyclopedia covers the views of certain psychoanalytic pioneers, such as the essay on Melanie Klein written by the authority on Kleinian theory, Hannah Segal. There are similar articles on the views of Lacan, Kohut, and others.
