Introductory matter is in German, English and French. The catalogue includes works in all media: paintings, drawings, collages, frottages, and sculpture. Volume 7 (published 2007) covers the artist's last years and his residence in the south of France. Only works that could be identified by photographs have been included. The critical apparatus is very thorough, but there are is no critical commentary. See "Max Ernst: Collagen, Inventar und Widerspruch", which is essentially a companion volume to the series, though published separately. Also see the documentary supplement volume: "An Autobiographical Collage" (New York, London, 2006).
