Compared to other avant-garde movements that emerged in the 1960s, conceptual art has received relatively little serious attention by art historians and critics of the past twenty-five years—in part because of the difficult, intellectual nature of the art. This lack of attention is particularly striking given the tremendous influence of conceptual art on the art of the last fifteen years, on critical discussion surrounding postmodernism, and on the use of theory by artists, curators, critics, and historians. This landmark anthology collects for the first time the key historical documents that helped give definition and purpose to the movement. It also contains more recent memoirs by participants, as well as critical histories of the period by some of today’s leading artists and art historians. Many of the essays and artists’ statements have been translated into English specifically for this volume. A good portion of the exchange between artists, critics, and theorists took place in difficult-to-find limited-edition catalogs, small journals, and private correspondence. These influential documents are gathered here for the first time, along with a number of previously unpublished essays and interviews.
