This volume has become known as perhaps the best introduction to Jung's work. In these famous essays. "The Relations between the Ego and the Unconscious" and "On the Psychology of the Unconscious," he presented the essential core of his system. Historically, they mark the end of Jung's intimate association with Freud and sum up his attempt to integrate the psychological schools of Freud and Adler into a comprehensive framework. This is the first paperback publication of this key work in its revised and augmented second edition of 1966. The earliest versions of the Two Essays, "New Paths in Psychology" (1912) and "The Structure of the Unconscious" (1916), discovered among Jung's posthumous papers, are published in an appendix, to show the development of Jung's thought in later versions. As an aid to study, the index has been comprehensively expanded.

As a current record of all of C. G. Jung's publications in German and in English, this volume will replace the general bibliography published in 1979 as Volume 19 of the Collected Works of C. G. Jung. In the form of a checklist, this new volume records through 1990 the initial publication of each original work by Jung, each translation into English, and all significant new editions, including paperbacks and publications in periodicals. The contents of the respective volumes of the Collected Works of C. G. Jung and the Gesammelte Werke (published in Switzerland) are listed in parallel to show the interrelation of the two editions. Jung's seminars are dealt with in detail. Where possible, information is provided about the origin of works that were first conceived as lectures. There are indexes of all publications, personal names, organizations and societies, and periodicals.
