he Collected Works of C. G. Jung is a book series containing the first collected edition, in English translation, of the major writings of Swiss psychiatrist Carl Gustav Jung. The volumes were edited and translated from the original German by Gerhard Adler and R.F.C. Hull, occasionally with assistance from others. Most were not written by Jung as books, but are collections of papers, essays, lectures, letters, etc. written by Jung from 1902 until his death in 1961, and compiled by editors from 1945 onward.The series contains revised versions of works previously published, works not previously translated, and new translations of many of Jung's writings. Several of the volumes are extensively illustrated; each contains an index and most contain a bibliography. Prior to Jung's death he supervised the revisions of the text, some of which were extensive.An enormous body of Jung's work still remains unpublished.
