Book Drum has launched a crowd-sourced literary world atlas, with pop-up text and pictures to illustrate each literary setting. That is designed to answer questions like: Where might Holden Caulfield and Esther Greenwood have crossed paths? How close did Captain Corelli come to the home of Odysseus? What is a Russian doing in Cambridge? Where did Robinson Crusoe come ashore? And just how far would the Snow Goose have to fly to reach Brave New World's lighthouse?
