The work on this bibliography was carried out mostly in 2002. Though it aims at being exhaustive, the research in different languages and translations may not have yielded every document and some may still be unknown to me. It is also likely that more material have been translated since. Besides, the Spanish and Brazilian-Portuguese literature has not been researched. This is why this bibliography must be considered as a ‘work in progress’ which any addition can only enrich.
Victor Ovcharenko has made a list of the writings of Sabina Spielrein starting with 1911, the year of her medical thesis in Zürich, and covering the years to 1931. He points out, however, that between the date of the last paper that she is known to have written and her death in 1942, there are eleven years and that it would be truly astonishing if she had neither written nor published anything during that period. Up to this date no document by her during that time has been found (Journal of Analytical Psychology, 44, 3, 1999).
