'Commoning Art' brings contemporary commons and art discourses into dialogue through feminist, queer, ecosocial, and critical studies perspectives. It outlines three positions in current practice: Art for Commons, centering the commons as a political and aesthetic concern; Art as Commons, challenging ownership and copyright; and 'Commoning Art', approaching art as an ongoing process of collective self-organization. Drawing on a variety of situated examples from artistic and curatorial practice, the transdisciplinary team of authors develops a methodology that advances an ontological reorientation of art, shifting away from the myth of individual autonomy toward forms of practice grounded in relationality and interdependence.
