"This wonderful new book by Elizabeth Bott Spillius, Jane Milton, Penelope Garvey, Cyril Couve, and Deborah Steiner provides us with a detailed exploration of Kleinian ideas. The book emerges from a framework that emphasizes the systematic refinement of basic concepts, the tie to Freud’s writings, and the adoption and subsequent elaboration of these ideas by other psychoanalytic schools. The New Dictionary of Kleinian Thought is an exemplar of clear thinking and impeccable research that offers the reader — whether a newcomer to the Kleinian model, or someone well schooled in this tradition — not only mere definitions of terminology, but also (and perhaps more important) a comprehensive appreciation of the impressive reach and depth of this line of thinking. ... This is a wonderful resource for those interested in a truly comprehensive explanation of Kleinian ideas, including their incubation, subsequent enhancement, and impact on the psychoanalytic world. The book deserves a special place on the shelves of analysts of all persuasions."- Lawrence J. Brown, The Psychoanalytic Quarterly
