For a long time, it was believed that the course catalogs of the University of Königsberg had been lost. This reprint makes them available for the first time and at the same time provides a detailed breakdown of them in several indexes. These catalogs enable us to trace the intellectual life at the university in the 18th century and at the same time give us a vivid picture of the scientific and cultural life of East Prussia, most of whose historical traditions have been lost since 1945. The complete accessibility of the Königsberg catalog is of great significance for the study of Kant.
