The Discworld Mapp is an atlas that contains a large, fold out map of the Discworld fictional world, 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. It was originally conceived as the second in a series of three maps, along with The Streets of Ankh-Morpork and A Tourist Guide to Lancre. For this work, Briggs became known as the "cartographer of Discworld." A fourth atlas, Death's Domain, was added to the series.
