Here are two elusive pieces of the context of midcentury American poetics. The Robert Duncan/Charles Olson letters have been available, until now, only in the brief reviews of each other that the poets extracted from them (“near-far Mister Olson” and “Against Wisdom as Such”), passages quoted by scholars who have been able to visit the archive at Storrs, and handfuls in Sulfur, Poetry, and Olson’s Selected Letters.
