Our network member Nathanael Busch (Institut für deutsche Philologie des Mittelalters, Universität Marburg) wrote an article together with Diana Müller (Universitätsbibliothek Marburg, Universität Marburg) on the topic of authority control for the humanities. The article is titled “Normdaten in den Geisteswissenschaften” and provides information on the structure, purpose and use of authority control. It also introduces the authority file Gemeinsame Normdatei (GND), which is widely used in the German-speaking area, and explains how the GND data can be used for research projects as well as the conditions under which researchers can actively process the GND.
