This collection contains eighteen essays written by Buchloh over the last twenty years. Each looks at a single artist within the framework of specific theoretical and historical questions. The art movements covered include Nouveau Realisme in France (Arman, Yves Klein, Jacques de la Villegle), art in postwar Germany (Joseph Beuys, Sigmar Polke, Gerhard Richter), American Fluxus and pop art (Robert Watts and Andy Warhol), minimalism and postminimal art (Michael Asher and Richard Serra), and European and American conceptual art (Daniel Buren, Dan Graham). Buchloh addresses some artists in terms of their oppositional approaches to language and painting, for example, Nancy Spero and Lawrence Weiner. About others, he asks more general questions concerning the development of models of institutional critique (Hans Haacke) and the theorization of the museum (Marcel Broodthaers); or he addresses the formation of historical memory in postconceptual art (James Coleman).
