Discworld

Discworld is a collection of fantasy comedy novels, graphic novels, short stories, and associated works conceived and primarily written by the English author Terry Pratchett. They are united by their being set on the Discworld, a flat planet balanced on the backs of four elephants which in turn stand on the back of a giant turtle. The novel series consists of forty-one books, the first being The Colour of Magic, published in 1983, and the last ''The Shepherd's Crown'', published posthumously in 2015. Pratchett also wrote eleven short stories related to the Discworld. The novels often satirise classic fantasy and science fiction, mythology, and folklore, and also include commentary on contemporary cultural, political and scientific issues.

The series has spawned a number of supplementary works, including four books on the science of Discworld, four maps of locations within it, and an encyclopedia. While Pratchett was involved with most of these, he often worked in collaboration with others including Stephen Briggs, Ian Stewart, Jack Cohen, and long-time series illustrators Josh Kirby and Paul Kidby. There is no intention to publish further novels following Pratchett's death, but supplementary works continue to be published and include ''Tiffany Aching's Guide to Being a Witch,'' by Pratchett's daughter Rhianna and Gabrielle Kent. In addition, Discworld novels have been adapted into computer games, board games, and for the theatre and television.
