‘In this collection of short essays, Pomeranz and Topik masterfully depict the story of the creation of the world economy. Without using academic jargon, they explain how trade with commodities, drugs, animals, people and ideas moved among continents and transformed the world.’ — Manel Ollé, associate tenure professor in Modern and contemporary Chinese history and culture, Director of the Master in Chinese Studies, Universitat Pompeu Fabra, Barcelona, Spain ‘How invisible networks of trade ultimately came to compel producers, merchants, and even whole societies to adapt to the networks' needs as they grew is a fascinating story, and one just as important for understanding the world as developments in politics or culture are. I know of no other book that introduces trade networks so well. It is an ideal text for survey courses.’ — Roland Spickermann - Chair, Dept. of History, University of Texas of the Permian Basin, USA
