In this month’s issue of National Geographic Traveler, Shannon’s article, “The Urban Reader,” takes a look at four lesser-known literary cities. Some things for book lovers to do: tour the awe-inspiring Library of Congress in Washington, D.C.; visit poet Pablo Neruda’s house (built for his mistress and muse) in Santiago; dine in a historic cellar restaurant in Stockholm’s Old Town, a longtime haunt of members of the Swedish Academy, which selects the Nobel Prize in literature recipients; and block out time to browse at Blackwell’s Bookshop in Oxford, England, where a single room houses more than 160,000 books. A bonus: places to track down Sir Arthur Conan Doyle’s famous detective in London, in anticipation of the December big-screen release of Sherlock Holmes: Game of Shadows.
