This book introduces the Internet through a systematic geographical interpretation, thus shedding light on the Internet as a spatial entity. The book approach is to extend basic concepts developed for terrestrial geography to cyberspace, most notably those relating to space, structure, place, distance, mobility, and presence. It further considers the Internet by its constitution of information space, communications space, and screen space. By using well-known concepts from traditional human geography, this book proposes a combination of terrestrial and virtual geographies, which may in turn help in coping with Internet structures and contents. The book appeals to human and economic geographers, especially those interested in information and Internet geographies. It may also be of special interest and importance to sociologists and media scholars and students dealing with communication technology and the Internet.
