The necessity to provide research with a specialized research tool as well as an institutional and transnational research tool has not yet been taken into account. The “Index Librorum Civitatum” (ILC) is intended to help bridge the gap between archival materials, finding aids and literature / editions in a single online presentation. For the “five new” federal states, the ILC can already be used as a research and demonstration tool. The federal states of Lower Saxony, Schleswig-Holstein, Hamburg and Bremen will be developed for the database from 2016 to 2019. In addition, the city maps of the historical countries or provinces of Silesia, Brandenburg and Pomerania are included in a parallel research project.
