The digitalisation of scientific processes is closely linked with the opening of sciences for participative formats on various levels. Citizen Science or community science approaches respectively are becoming increasingly important in history studies. This volume offers a practical insight into both infrastructures and various project approaches in historical research. Potentials and challenges in the conception, implementation and realisation of historically oriented citizen science projects are illuminated and criteria for success and future perspectives are elaborated. The volume thus aims to contribute to the debate on the use of citizen science as a method within historical research.
