This catalogue reproduces all of the artist's known correspondence, excerpts from his writings, and other archival documents related to Klimt's life and work, including critical reviews by Klimt's contemporaries. A German edition was issued simultaneously. The catalogue raisonné presents approximately 245 paintings with the most current information available; including several early works not covered in the three previous oeuvre catalogues of the artist's work (Novoty & Dobai, 1967-1968-1975 and Weidinger, 2007- see entries cited in this database). However, the present study does not consider works on paper.
