The Library of Congress’s map blog, Worlds Revealed, has begun a series of posts about imaginary maps. “We’ll be exploring all of these types of maps and imaginary worlds this summer. Come revisit the Hundred Acre Wood and the other worlds of your favorite children’s stories, spend some time in medieval Europe, and run from White Walkers in Game of Thrones.” So far we have an introduction and a look at maps from the European Middle Ages and Renaissance, with Tolkien’s map of Middle-earth next on the schedule.
