The Working Group (WG) on Exonyms of the United Nations Group of Experts on Geographical Names was established in 2002. The papers in this volume of Name & Place, marking the 19th Meeting of the WG in Prague in 2017, represent a cross-section of the knowledge acquired after 15 years of collective activities, in which the WG has developed – and hopefully enhanced – its understanding and appreciation of the subject of exonyms with the sub-themes usage, standardization, definitions, and criteria. This volume, edited by Peter Jordan, Irena Švehlová & Paul Woodman, returns to the subject of exonym usage, through papers which reveal a survey of the circumstances under which exonyms are deployed in individual countries today.
