As the keepers of the Vinland Map, the folks at Yale’s Beinecke Library might be expected to have a few thoughts about map forgeries, seeing as the Vinland Map is arguably the best known example. In an article posted to the Beinecke Library website last July, Raymond Clemens discusses the work of Yale’s Institute for the Preservation of Cultural Heritage to determine the Vinland Map’s inauthenticity, and detecting map forgeries in general. Yale seems to be making a point of studying map forgeries, to the point of adding known forgeries to their collections.
