In addition to the catalogue raisonné of approximately 1,200 drawings, the publication includes an essay on papers and watermarks in Purrmann's works, with a separate catalogue of watermarks. The Appendix provides a discussion of signatures and stamps, and a "List of Preliminary Drawings on Canvas and of Watercolors with Posterior Designs." The catalogue raisonné is organized by subject: portraits, landscapes, still-lifes, interior scenes, nudes, and designs. There is also a section on questionable attributions.
