Book excerpt: Provenance matters like never before. Legal regimes regulating the use of Geographical Indications (GIs) protect commercially valuable signs on products - such as Darjeeling and Champagne - which signal the link to their regions of origin. Such regimes have been controversial for over a century. A rich, interdisciplinary work of scholarship, this Research Handbook explores the reasons for and consequences of GIs existing as a distinct category within intellectual property (IP) law. Historians, geographers, sociologists, economists and anthropologists join IP specialists to explore the distinguishing feature of GIs, that certain products are distinctively linked or anchored to specific places.
