Financed by the Federal Ministry of Education and Research (BMBF), a comprehensive digitization project took place at the Graphic Collection from December 2017 to November 2020. The project was dedicated to the core of the collection, the nearly completely preserved landgrave's copperplate engraving cabinet, and was successfully completed with the publication of the inventory in the form of a. Database could be completed.

Until the 19th century, prints were mostly stored bound in large folios. Originally housed together with the library of Wilhelm IX (1743–1821), later Elector Wilhelm I, in Wilhelmshöhe Palace, the Graphic Collection has preserved almost 50 adhesive-bound volumes organized by artists or schools, as well as ten folios containing printed portraits. Apart from the historical table of contents, the volumes remained unexplored. Alongside representative publications, the collection served the Landgraves as a pictorial reference work.

The project presents the approximately 14,000 engravings preserved in the volumes to the public and research for the first time. For further information, please contact the head of the Print Collection, Dr. Christiane Lukatis.
