Unfortunately (for me at least), the recently re-recorded collection (by the Pratchett estate) using different voice artists (Indira Varma, Peter Serafinowicz, Bill Nighy, Steven Cree) don't capture the same 'magic' as the original voices and often fail to recognise and pronounce the subtle double and triple entendres (e.g. of the Nac Mac Feegles) - which suggests they and the editors don't fully appreciate the humour Pratchett intended.
Don't miss the "The Science of Discworld" series (book I (1999), II:The Globe (2002), III:Darwin's Watch (2005), IV:Judgement Day (2013)) where the chapters alternate between stories of the Wizzards (voiced by Stephen Cohen) of Unseen University accidentally creating Roundworld (Earth and our universe) and then tinkering with its evolutionary timeline in a battle with the Elves, eventually leading to humans leaving the planet using a Space elevator, and serious explanation and exposition of the sciences by Jack Cohen and Professor Ian Stewart (voiced by Michael Fenton-Stevens).
Those make a great introduction to science for kids young and old!
"The Folklore of Discworld" and some of the loosely related stories such as Mrs Bradshaw's Handbook (voiced by Penelope Keith - a skit on the Victorian era "Bradshaw's" railway travel guide [2] and a spin-off from "Raising Steam", featuring her travels on the Ankh-Morpork and Sto Plains Hygienic Railway), "The World of Poo" (Sam Vimes son's fascination with collecting poo specimens) and, unrelated to Discworld but written in the same tongue-in-cheek style "Dodger", a tale set in Victorian London featuring a lovable Tosher discovered by 'Charlie' (Charles Dickens).
