Our specialized inventory encompasses circa 130,000 volumes on the art of the 20th and 21st centuries, and is one of the largest such collections in North Rhine-Westphalia.

The inventory is oriented toward the acquisition priorities of the Kunstsammlung Nordrhein-Westfalen: the spectrum includes monographs, exhibition, inventory, and raisonné catalogues, museum and gallery publications, reference works, videos, CDs, DVDs, and professional reviews.

One special focus is literature on the artists and creative movements that are represented in the museum's permanent collection. Purchased alongside new publications are earlier items of primary and secondary literature.
