A few examples abound. I think they discuss what needs to be done with dead bodies as part of being a witch in either A Hat Full of Sky or Wintersmith.
And not to detract from the Discworld and its Death, but there are also many of Neil Gaiman's works that deal with Death, Loss, and Bereavement. A lot of The Sandman graphic novel series deal with the subject (particularly the stories "The Sound of Her Wings" from Preludes & Nocturnes, "Facade" from Dream Country, "The Song of Orpheus" from Fables & Reflections, "Cerements" from Worlds' End, and the entirety of The Wake). One of the key characters is Death of the Endless, the sister of Dream of the Endless.
The Doctor: There's one thing you never put in a trap, if you're smart, if you value your continued existence, if you have any plans about seeing tomorrow, there's one thing you never, ever put in a trap... Me.
