These volumes document 395 entries, including doubtful and rejected works. There are illustrations of every state, locations are indicated, and the works are numbered. Individual catalogue entries include title, inscriptions, states, medium, dimensions, and comments. There is also a concordance to C. Middleton (1878) and the Illustrated Bartsch. The text volume containing the catalogue raisonné, but not the Atlas, is available in full-text view. A supplement to this publication by N. Chechulin was also published in 1914 (cited in this database).
