This is the final addendum to the multi-volume catalogue raisonné of Wassily Kandinsky (see references in this database to Roethel, 1970; Rothel and Benjamin, 1982; Barnett et al., 1992–94; and Barnett, 2006). In addition to the catalogue, the Addendum includes a short essay by Vivian Endicott Barnett, "The Conclusion of the Kandinsky Catalogue Raisonné."
