The Kollwitz Museum Köln has the worldwide largest collection of the artist’s works. One of its objectives is to open up new access paths to her art and to illustrate the high artistic quality of her drawings, graphic art and sculptural works.
The first catalogue raisonné of Kollwitz's sculptural work: the reference literature on the artist's three-dimensional œuvre — as a book and as a downloadable PDF catalogue
In 2002, Galerie Kornfeld Verlag, Bern, published a completely revised catalogue raisonné of her prints — a two-volume standard work in Kollwitz’ resarch
The authoritative scholarly publication on the artist's finished and self-contained drawings, as well as her sketches, designs and study sheets
The archive of the Kollwitz Museum Köln holds an extensive collection of photographs, including pictures from the artist's family albums, which come from her estate. It also comprises autographs, historical picture postcards, publications and further archival materials
The holdings of the research library at the Kollwitz Museum Köln comprise well over 3,000 volumes — exhibition catalogues, bulletins, monographs, reference works, periodicals and more
