I am especially indebted to Josh Billings, my coeditor for the Norton Critical Edition, who offered much sage advice and encouragement (and even remarked on one passage as “like Emily Dickinson”!). Claire Catenaccio and Arabella Currie also made many helpful observations on the draft version. At Norton, Carol Bemis has been a great champion, and I am also grateful to Marie Pantojan, Rachel Goodman, Bonnie Thompson, and Harry Haskell for their various roles in producing the volume. At home, above all, I have to thank Beaty, as ever, for her love and support, Charis for keeping me alert, and Phoebe and Nat for keeping in touch.
