On March 25th, 2010, EDP Sciences celebrated its 90th anniversary on the Melody Blues, a barge situated in front of the "Bibliothèque François Mitterrand", an emblematic venue of knowledge. This celebration was the opportunity to go back to the development of our publishing house, its evolution, its mission towards scientific communities, but also to reflect on the future of scientific publishing thanks to a dialogue with the most directly affected: authors, researchers, students and industrialists.
