Out today: Zoran Nikolic’s Atlas of Unusual Borders (Collins), a book that “presents unusual borders, enclaves and exclaves, divided or non-existent cities and islands.” Another compendium of geographical curiosities: a genre we’ve seen before (see, for example, the Atlas of Improbable Places, Atlas Obscura, the Atlas of Remote Islands, the Atlas of Cursed Places, Beyond the Map or Unruly Places/Off the Map) except this time it’s about borders.
