In 2003/04, Philipp Gutbrod published his catalogue raisonné of Wols’ works on paper as a doctoral thesis at the University of Heidelberg.

Philipp Gutbrod: Wols (1913-1951) – Die Arbeiten auf Papier (Kommentiertes, kritisches Werkverzeichnis)
(Wols - Works on Paper, Catalogue Raisonné), Vol. I-IV, Heidelberg (Dissertation) 2004.

Incorporated into this thesis was the Wols-archive of the art-historian Werner Haftmann (founder of the documenta and first director of the Neue Nationalgalerie in Berlin), who began working on Wols in the early 1950s.
In some cases, Gutbrod's opinion regarding the authenticity of a work on paper differed from Haftmann's assessment. Therefore, next to Gutbrod's published opinion, each entry of the catalogue raisonné states if Haftmann was intending on including the work into his original (unpublished) catalogue raisonné or not.

Questionable and fake works on paper were also published, albeit in separate sections, because numerous forgeries are spread out all over the world and have found their way into respected collections. This is due to the fact that Wols’ wife, Gréty Wols, was heavily involved in the production and distribution of fake works
shortly after Wols' death. In the thesis, letters have been published giving insight into these actions.

As new research develops and unknown works by the artist are discovered, the work on this catalogue raisonné  continues. A publication in a publishing house is planned for the future.

At the moment, the catalogue can be consulted at several university libraries in Germany, e.g. in Heidelberg, Frankfurt/Main, and Cologne.
