The Complete Poems of A.R. Ammons
Edited by Robert M. West (Norton)
This monumental and authoritative two-volume set collects every poem the prolific Ammons ever published. Ammons continued the American vernacular tradition of Whitman and Williams, pushing it in unexpected directions. His poems were humorous and contemplative, concerned with feeling and natural processes. These books are large and sprawling and unwieldy, which is probably how Ammons would've wanted it.
