This edition, that includes the participation of Marcelo Expósito (Spain-Argentina) and Javier Gil (Colombia) as guest editors, brings together the thoughts and ideas of Luis Ignacio García (Argentina), Brian Holmes (United States), Javier Toret (Spain) and Colombian authors Ludmila Ferrari and Carlos Uribe. This issue, like many other ERRATA# before, contains two aspects of thought that stand out, the first deals with the subjects of collective creation and collaborative practices from the perspective of activism and social movements; the second explores art collective as a community or directed to social groups with specific needs. However, both come together under the perspective of art as the engine of social and cultural transformation.
