The Discworld books can be split up into several mini-series, based on the main characters: * The Rincewind books (featuring Rincewind and The Luggage.) * The Witches books (featuring Granny Weatherwax, Nanny Ogg et al). * The Death books (featuring Death and Susan Sto Helit, often against the Auditors). * The City Watch books (featuring Sam Vimes and the rest of the Watchmen). * The Post Office books (featuring Moist Von Lipwig and the staff of whichever service he's working for). * The Wee Free Men books (the children's Discworld series with Tiffany Aching and the Nac Mac Feegle). * Other, one-off books which are still Discworld stories, but feature characters who don't usually take centre stage.
