A unique set of conditions produced in both space and time and ranging across material, social, political and economic relations, Situation is now a key concept in 21st-century art. This anthology traces its evolution from the 1960s emergence of site-specific art to its divergent implications in the global era. Among the topics surveyed are the limits of site; the role of the artist as ethnographer or fieldworker; the relation between action and public space; the meaning of place and locality; and the crucial role of the curator in new situation-specific art.
