The Discworld Atlas

In this noble endeavour, drawing upon the hard won knowledge of many great and, inevitably, late explorers, one may locate on a detailed plan of our world such fabled realms as the Condiment Isles, trace the course of the River Kneck as it deposits silt and border disputes in equal abundance on the lands either side, and contemplate the vast deserts of Klatch and Howondaland - a salutary lesson in the perils of allowing ones goats to graze unchecked.
