He published his first short story at thirteen and wrote more than 70 books.

His books include Carpe Jugulum, Dodger, Equal Rites, Eric, Going Postal, Good Omens (with Neil Gaiman), Guards! Guards!, Hogfather, Making Money, Men at Arms, Mort, Raising Steam, Reaper Man, Snuff, The Carpet People, The Colour of Magic, and The Wee Free Men. He also wrote the Bromeliad books Truckers (1989), Diggers (1990), and Wings (1990), and the Discworld companion mapps The Streets of Ankh-Morpork (1993), The Discworld Mapp (1995), A Tourist Guide to Lancre (1998), and Death's Domain (1999). Knighted in 2009 for services to literature, he was diagnosed with early-onset Alzheimer's disease in 2007 and campaigned for Alzheimer's research and assisted dying while continuing to write.
