Providing interdisciplinary and global perspectives, this book examines historical and contemporary changes in secondhand economies, including the emergence and specialization of secondhand venues, the materials involved, as well as the cultural significance of secondhand things and the professions associated with them. The objects in focus range from used clothing, scrap and waste materials, to antiquities and used cars, thrift stores and circular economies. Growing concerns with sustainability in the West have helped bring about the ‘rediscovery’ of practices of clothing re-use, re-purposing and re-cycling at the same time as major high-street retailers are establishing programs to return used clothing to their stores for re-sale or recycling. As the contributions to this edited volume demonstrate, recent concerns with the fast pace and adverse effects of global commodity flows have increased the scholarly attention to secondhand economies, both in terms of their history and their significance for livelihoods and sustainability. The chapters in this book were originally published as a special issue of the journal, Business History.
