Early in 1816, Jane Austen's brother Henry retrieved her manuscript 'Susan', an early version of
Northanger Abbey, from a publisher named Crosby, who had bought it from Jane for £10 thirteen years earlier but never published it. It's thought that Jane revised it during this year, and gave her heroine a new name - Catherine Morland. However, Jane may have felt that her novel was now rather out of date, because although she wrote an advertisement for the work, it was not published until after her death.
The second edition of Jane Austen's Mansfield Park was published by John Murray sometime in February 1816. (There are some fascinating documents relating to Austen in the John Murray Archive at the National Library of Scotland). The first edition, published by Egerton, had sold out fairly quickly but had not been reprinted, so Jane must have been hopeful that a more well-known publisher would help 'puff' her book.
However, in the event, Mansfield Park did not sell at all well, and Murray had to reduce the price. You can see some readers' opinions of Mansfield Park and Emma (published in December 1815) collected by Jane Austen here.
