When I worked on a national newspaper, an old, battered copy of The Times Atlas of the World stood propped against the Comment desk. The red cloth binding had come off and the signatures had fallen apart, like breakaway provinces seceding from a crumbling empire. As various benighted places – Darfur, Basra, Helmand – were thrust into the headlines, our reporters and subs would make off with the relevant pages. This battered relic featured countries that no longer existed: Czechoslovakia, the German Democratic Republic, Yugoslavia and, sprawling across a third of the planet, the Union of Soviet Socialist Republics.
