An extensive digitalisation project with a particular focus on the Kupferstichkabinett, the landgraves' collection of prints and drawings that represents the heart of the collection and has survived almost completely intact, ran from December 2017 to November 2020. It was financed by the Bundesministerium für Bildung und Forschung (BMBF, Federal Ministry of Education and Research) and was successfully completed with the publication of the repository in the form of a database.

Right up until the 19th century, prints and drawings were usually stored in large bound folios. Formerly housed in Schloss Wilhelmshöhe palace together with the library of Landgrave William IX, later William I, Elector of Hesse (1743–1821), almost 50 albums arranged according to artists or schools as well as ten folios with portrait prints have survived to form the collection of prints and drawings. Three of the albums had never been examined before, apart from their historic tables of contents. Together with prestigious works issued by publishing houses, the collection served the landgraves as a visual encyclopaedia.

The project presents the collection's approx. 14,000 surviving prints and drawings to the public for the first time. Please contact the head of the collection of prints and drawings, Dr. Christiane Lukatis, for more detailed information.
