When White left to edit "Appleton's Magazine", he was replaced by Karl Edwin Harriman, who edited "The Red Book Magazine" and its sister publications "The Blue Book" and "The Green Book" until 1912. Under Harriman the magazine was promoted as "the largest illustrated fiction magazine in the world" and increased its price from 10 cents to 15 cents. According to Endres and Lueck (p. 299), ""Red Book" was trying to convey the message that it offered something for everyone, and, indeed, it did... There was short fiction by talented writers such as James Oliver Curwood, Jack London, Sinclair Lewis, Edith Wharton and Hamlin Garland. Stories were about love, crime, mystery, politics, animals, adventure and history (especially the Old West and the Civil War)."
