This special edition celebrates twenty-five years of the <I>Best American Poetry </I>series, which has become an institution. From its inception in 1988, it has been hotly debated, keenly monitored, ardently advocated (or denounced), and obsessively scrutinized. Each volume consists of seventy-five poems chosen by a major American poet acting as guest editor—from John Ashbery in 1988 to Mark Doty in 2012, with stops along the way for such poets as Charles Simic, A. R. Ammons, Louise Glück, Adrienne Rich, Billy Collins, Heather McHugh, and Kevin Young. Out of the 1,875 poems that have appeared in <I>The Best American Poetry</I>, here are 100 that Robert Pinsky, the distinguished poet and man of letters, has chosen for this milestone edition.
