The first two books, Psychological Types and Jung's Compass of Psychological Types, are required for the Gifts Compass training in psychological types. Two other books, Two Essays on Analytical Psychology, and Introduction to Jungian Psychology are recommended.

Psychological Types
Carl Gustav Jung

Jung called this book "the fruit of nearly twenty years' work in the domain of practical psychology." In his autobiography he wrote: "This work sprang originally from my need to define the ways in which my outlook differed from Freud's and Adler's. In attempting to answer this question, I came across the problem of types; for it is one's psychological type which from the outset determines and limits a person's judgment. My book, therefore, was an effort to deal with the relationship of the individual to the world, to people and things. It discussed the various aspects of consciousness, the various attitudes the conscious mind might take toward the world, and thus constitutes a psychology of consciousness regarded from what might be called a clinical angle."


Jung's Compass of Psychological Types
James Graham Johnston

The Gifts Compass training for professionals is organized to correspond to the chapters in this book. Stories, examples, tables, diagrams, and biographical sketches help to make Jung's treatise on psychological types memorable and understandable. This book and Jung's Psychological Types are the two required books for the training.

Jung's Compass of Psychological Types links the tangible frameworks of typology to the intangible networks of depth psychology to explain the use of psychological types for the union that Jung termed "individuation"—becoming a uniquely whole person.


Two Essays on Analytical Psychology
Carl Gustav Jung

This volume, Volume VII of the Collected Works, was actually written before Volume VI, Psychological Types. It serves as a readable introduction to Jung's full model. In these two famous essays. "The Relations between the Ego and the Unconscious" and "On the Psychology of the Unconscious," he presents the essential core of his system. Historically, they mark the end of Jung's intimate association with Freud as they sum up his attempt to integrate the psychological schools of Freud and Adler into a comprehensive framework.


Introduction to Jungian Psychology: Notes on the Seminar Given in 1925
Carl Gustav Jung

In 1925, while transcribing and painting in his Red Book, C. G. Jung presented a series of seminars in English in which he spoke for the first time in public about the genesis of his psychology and the self-experimentation he called his "confrontation with the unconscious." These seminars constitute an introductory overview of his ideas about psychological types and the archetypes of the collective unconscious. The notes from these seminars form a clear and important account of the development of his work.
