Joan Didion and John Gregory Dunne met in the late fifties, when she was working at Vogue and he at Time. They married in 1964, and in 1966 they adopted a baby girl, giving her a name from the Yucatán: Quintana Roo. Together, Didion and Dunne lived out one of the most collaborative literary marriages in American history. Last week, after two years of preparation, the New York Public Library opened the Didion-Dunne archive to the public. Among its three hundred and thirty-six boxes of material is a thick file of typewritten notes by Didion describing her sessions with the psychiatrist Roger MacKinnon, beginning in 1999. Addressed to Dunne, the entries are full of direct quotations and written with the immediacy of fresh recollection. Didion was concerned about Quintana and her struggles with depression and alcoholism, but she was preoccupied, too, with aging, with creative fulfillment, with the complex dynamics of their family. She recorded her thoughts with the cool, forensic clarity she was known for.
