Correspondence primarily between Phipson, McElderry, Judy Long, and Marni Hodgkin of Macmillan London, which co-published this novel with Atheneum, though under the title Keep Calm. Hodgkin left Macmillan in the middle of the publication process and correspondence resumes with Diane Denney, the new editor. Macmillan and Atheneum worked more separately than usual on this title, with Macmillan "rushing ahead" (in McElderry's words) to publish in England by spring, while the American edition was published in the fall. Most of the correspondence focuses on edits to the manuscript, though Phipson and McElderry also discuss their personal lives, including the death of McElderry's husband and the honorary doctorate she received from Mt. Holyoke. There is also correspondence with Lewis Victor Mays, who did the jacket art, and representatives at Curtis Brown, Phipson's agent. Two letters regarding other Phipson titles, Fly into Danger and The Bird Smugglers can be found at the end of the file, along with several reprints of artwork with unclear relation to When the City Stopped.
