When James Edward Austen-Leigh’s Memoir of his famous aunt was published in 1870, far from satisfying public curiosity about Jane Austen as the family had intended, it simply raised a series of new questions, particularly about Jane Austen’s unpublished work, which had been mentioned only in passing. Austen Leigh was persuaded to issue a much-expanded second edition in 1871. Here he included for the first time the complete texts of Jane Austen’s novel in letters, Lady Susan, and the fragmentary novel The Watsons, as well as a brief summary of her last unfinished work, later known as Sanditon. At the same time he took the opportunity to revise the biographical sections of the Memoir partly to include new information that had come to light since the first edition, so that all in all the second edition has a significance for Austen scholars quite separate from the first.
