He immediately began work on "Barchester Towers", the second Barsetshire novel; upon its publication in 1857, he received an advance payment of £100 (about £ in consumer pounds) against his share of the profits. Like "The Warden", "Barchester Towers" did not obtain large sales, but it helped to establish Trollope's reputation. In his autobiography, Trollope writes, "It achieved no great reputation, but it was one of the novels which novel readers were called upon to read." For the following novel, "The Three Clerks", he was able to sell the copyright for a lump sum of £250; he preferred this to waiting for a share of future profits.
