While poking around the University of Chicago Press website yesterday, I noticed that a fourth edition of Norman J. W. Thrower’s history of cartography textbook, Maps and Civilization: Cartography in Culture and Society, is due out this month: Amazon. The changes from the third edition (Amazon, iBooks) appear to be limited: “For the fourth edition of Maps and Civilization, Thrower has added an additional chapter that serves to bring the volume completely up to date.” My gaps in cartographic knowledge are such that I’ve never read this book; this may be an opportunity to rectify that.
