The Discworld Mapp is an atlas that contains a large, fold out map of the Discworld (sold by Cut-Me-Own-Throat Dibbler) drawn by Stephen Player to the directions of Terry Pratchett and Stephen Briggs. It also contains a short booklet relating the adventures and explorers of the Disc and their discoveries.

The Discworld Mapp can be classed as a book or short story of Pratchett's and is a very useful resource for people that read the book and play Discworld MUD and GURPS.
