The Colin Smythe/Terry Pratchett Collection at Senate House Library comprises over 3,000 items, including all his novels; first editions, in print and audio, translated into more than 40 languages and for different markets; posters; letters; annotated typescripts of his works; news cuttings; adaptations of his works as computer and video games; television, radio and stage productions; original illustrations for both novels and video games; as well as many ephemera that depict the worlds he recreated in his books. The collection is still growing, as new material arrives from Colin Smythe, Pratchett's first publisher and literary agent, who has donated most of the items to SHL.
