The Modern Archives, King's College, Cambridge University contain a carbon copy of a three-page single spaced manuscript with the title “A Passage From The Autobiography of an Analytical Economist” (RFK/16/2/134–139, hereinafter “Autobiography”). Joan Robinson's initials are typed at the end of the document, which is dated October 1932.

In October 1932, Heffer, the Cambridge University student bookstore, published Joan Robinson's methodological pamphlet, Economics is a Serious Subject, and she delivered the manuscript of The Economics of Imperfect Competition to Macmillan (Joan Robinson to Richard Kahn, October 30, 1932, RFK/13/90/1/19). The Autobiography was apparently drafted shortly after these two projects were completed. The typescript in Modern Archives, which seems to be the only extant copy, was not made until some months later. In a letter of March 2, 1933, Kahn suggested adding “a long section to your secret document if you can do so without spoiling it,” regretting that he had not asked her for a copy (RFK/13/90/1/162–67). She replied somewhat mysteriously, alluding to a superstitious reluctance to having it typed but admitting that eventually it would have to be done (March 23, 1933, RFK/13/90/1/205–208). Since the carbon copy refers to page 275 of her book, the Autobiography was not typed until she had seen the final set of page proofs, and perhaps not until the book had appeared.
