Book excerpt: Nostalgia is intimately connected to the history of the social sciences in general and anthropology in particular, though finely grained ethnographies of nostalgia and loss are still scarce. Today, anthropologists have realized that nostalgia constitutes a fascinating object of study for exploring contemporary issues of the formation of identity in politics and history. Contributors to this volume consider the fabric of nostalgia in the fields of heritage and tourism, exile and diasporas, postcolonialism and postsocialism, business and economic exchange, social, ecological and religious movements, and nation building. They contribute to a better understanding of how individuals and groups commemorate their pasts, and how nostalgia plays a role in the process of remembering.
