found: Encyc. Britannica online, January 9, 2015(Northanger Abbey, novel by Jane Austen, published posthumously in 1817. Northanger Abbey, which was published with Persuasion in four volumes, was written about 1798 or 1799, probably under the title Susan. In 1803 the manuscript of Susan was sold to the publisher Richard Crosby, who advertised for it, but, unaccountably, it was not published at that time.)
found: Wikipedia, January 9, 2015(Northanger Abbey was the first of Jane Austen's novels to be completed for publication; Susan (as it was first called) was written circa 1798-99; was revised by Austen for the press in 1803, and sold in the same year for £10 to a London bookseller, Crosby & Co., who decided against publishing; was further revised by Austen in 1817/18, with the intention of having it published; Northanger Abbey (as the novel was now called) was brought out posthumously in late December 1817 (1818 given on the title page); published with Persuasion)
