From 'Aql to Zwicky, here is the definitive biographical guide to poetry throughout the world in the 20th century. Over 900 entries by over 75 international contributors bring a global perspective to bear on modern verse, encapsulating the lives and works of a vast array of poets in precise, compact detail. By placing canonical poets alongside sometimes under-represented ones - Andre Breton alongside Jacqueline Risset, Adrienne Rich alongside Maurice Kenny - the volume juxtaposes the already familiar and the newly essential.
