Alongside attempts to write C. G. Jung's biography, endeavours were under way to publish his works. The fate of this project was to have critical and unsuspected consequences for subsequent biographies, and indeed, for all studies of Jung. For the volumes which have been produced: The Collected Works, several volumes of seminars and correspondences, leave much to be desired, and are glaringly incomplete. Those responsible for the Collected Works managed to make the bulk of Jung's published writings available in a comparatively short span of time from Jung's death. The reproduction of Jung's works was not without errors, and certain passages in the original editions were not reproduced in the Collected Works edition. Thus, what is supposed to be the text of the first edition of "The structure of the unconscious" of 1916 does not exactly correspond to what was published in the Archives de Psychologie.
