As its new, elaborated title suggests, "The World Today: Concepts and Regions in Geography" focuses on the geography of the world toward the close of the first decade of the twenty-first century and serves as a guide to geographic ideas and perspectives, past and present. Authors H. J. de Blij and Peter Muller continue in their tradition of providing authoritative content, currency, and outstanding cartography in a concise, technology-rich package with the third edition of "The World Today: Concepts and Regions in Geography". Thoroughly updated, the third edition includes a new, engaging and currency-driven photo program, expanded data, and a new chapter feature - What's Driving Geographic Change in the Realm.
