Co-Creation, a comprehensive publication, is part of an ongoing research project exploring co-creation and socially engaged art. Initiated in 2013 by Celine Poulin, Marie Preston, and Stephanie Airaud, it evolved through symposiums, seminars, and exhibitions. More than just symposium proceedings, this book shares insights from the project, filling a gap in French literature. It fosters international dialogue and documents collective work connecting French and global art institutions. It delves into questions like the role of popular education, power dynamics in group work, and evaluation methodologies in co-creation practices.
