The Luxembourg Centre for Contemporary and Digital History (C2DH), together with the European University Institute (Florence, Italy) and the Max Planck Institute for Legal History and Legal Theory (Frankfurt am Main, Germany), organises this Summer School to explore methods of oral history and to test digital tools, while it pays attention to how digital sources may shape narratives in contemporary European history. The ‘Oral history of European integration’ collection presents audio and video accounts from key players and observers of the European integration process. The interviews are chiefly conducted for academic purposes, to provide new primary sources for researchers specialising in European studies. These sources often represent a useful complement to existing resources and archive material, offering a new perspective. They also constitute an important legacy, as both the result of a process of academic research and the starting point for further investigation.
