- Going Postal is a fantasy novel by British writer Terry Pratchett, the 33rd book in his Discworld series, released in the United Kingdom on 25 September 2004. Unlike most of Pratchett’s Discworld novels, Going Postal is divided into chapters, a feature previously seen only in Pratchett’s children’s books and the Science of Discworld series. These chapters begin with a synopsis of philosophical themes, in a similar manner to some Victorian novels and, notably, to Jules Verne stories. The title refers to both the contents of the novel, as well as to the term ‘going postal’.
