The relationship between the IAAP (International Association for Analytical Psychology) and the JAP (Journal of Analytical Psychology) in the course of their 50-year old existence is explored from historical, theoretical, institutional, personal and clinical perspectives. This relationship is seen to have been contentious as well as complementary in promoting an interdisciplinary approach to Jungian clinical practice. The complementary aspects are evidenced in the training programmes of IAAP constituent Societies and in papers presented at the Cambridge Congress of 2001 and the Barcelona Congress of 2004. The role of the Journal in holding together different, sometimes divergent, views relating to Jung's concepts and theories, and in subjecting these views to discussion, debate and assessment as to their clinical relevance and effectiveness, is explored.
