This revised edition takes the theme of place as the unifying principle for a full account of the discipline at the beginning of the twenty-first century. The work comprises 64 substantial essays addressing human and physical geography, and exploring their inter-relations. The encyclopedia does full justice to the enormous growth of social and cultural geography in recent years. Leading international academics from ten countries and four continents have contributed, ensuring that differing traditions in geography around the world are represented. In addition to references, the essays also have recommendations for further reading. As with the original work, the new "Companion Encyclopedia of Geography" provides a state-of-the-art survey of the discipline and is an indispensable addition to the reference shelves of libraries supporting research and teaching in geography.
