The Digital Network of University Collections project explores the basis for a sustainable collection infrastructure within the four partner institutions and develops a recommendation for its sustainable development. A comprehensive digital infrastructure for approximately 90 collections aims to support their usability and visibility, as well as facilitate research. The project is led by Dr. Yong-Mi Rauch (Humboldt-Universität zu Berlin), Dr. Andreas Brandtner (Freie Universität Berlin), and Prof. Dr. Schnalke (Charité – Universitätsmedizin Berlin).
