Authority data provide standardized records and unique identifiers in the form of specific numbers that distinctly describe and categorize individuals, works, institutions, research funders, entities, or keywords. This standardization eliminates incorrect or duplicate assignments. Authority data is particularly useful in catalogs and databases, where it facilitates easy retrieval of information about specific entities and supports digital networking and discoverability across projects. In Germany, the “Integrated Authority File” (GND) by the German National Library is the central authority filei¹ see: https://www.dnb.de/DE/Professionell/Standardisierung/GND/gnd_node.html.
