In a research project on legal history, the Mannheim University Library digitized the newspaper “Deutscher Reichsanzeiger and Preußischer Staatsanzeiger” published between 1819 and 1945. The Publication contains official announcements, publications of the central commercial register and a stock exchange supplement. A full text search is available by processing the scans with OCR software.
