Emily Dickinson was a letter writer before she was a poet. And it was through letters that she shared prose reflections—alternately humorous, provocative, affectionate, and philosophical—with her extensive community. While her letters often contain poems, and some letters consist entirely of a single poem, they also constitute a rich genre all their own. Through her correspondence, Dickinson appears in her many facets as a reader, writer, and thinker; social commentator and comedian; friend, neighbor, sister, and daughter. is the first collected edition of the poet’s correspondence since 1958. It presents all 1,304 of her extant letters, along with the small number available from her correspondents. Almost 300 are previously uncollected, including letters published after 1958, letters more recently discovered in manuscript, and more than 200 “letter-poems” that Dickinson sent to correspondents without accompanying prose. This edition also redates much of her correspondence, relying on records of Amherst weather patterns, historical events, and details about flora and fauna to locate the letters more precisely in time. Finally, updated annotations place Dickinson’s writing more firmly in relation to national and international events, as well as the rhythms of daily life in her hometown. What emerges is not the reclusive Dickinson of legend but a poet firmly embedded in the political and literary currents of her time. Dickinson’s letters shed light on the soaring and capacious mind of a great American poet and her vast world of relationships. This edition presents her correspondence anew, in all its complexity and brilliance.
