Reviews of the French edition“In this beautifully produced book, which contains a separate section with fine reproductions of the main maps, Marie de Rugy has exposed the complexity of colonial cartography, with all its technical and human challenges, in a particularly critical way, thereby demonstrating the relevance of a comparative approach. Her research takes a fresh look at questions about centrality and periphery in cartographic matters.”East Asian Science, Technology, and Medicine, no.50, 2019, 184-186.“This enterprise was anything but easy (…) Marie de Rugy’s book is not only an excellent monograph on cartography in Asia at the end of the 19th century. It is also an inspiring reflection on the nature of the conquest and the transformation of imperial margins by European empires.”L’Histoire, no.458, April 2019.“This book delves into several colonial regimes and (…) offers a nuanced analysis of the interactions between colonisers and colonised peoples. Here lies its success.”Liens socios“By presenting a comparative approach, adopting a large questioning and delving into a huge variety of sources, the author offers a reference work.”La letttre de l’Afrase, no.96“Overall, it is a very original book, especially chapter 6 where the author analyses indigenous maps and immerse readers in the heart of the map production process”Revue d'histoire du XIXe siècle, no.58, 2019, 290-292.“Another asset of this research is the constant attention given to the interaction between colonial cartographers and the local inhabitants in the gathering of general and specific information about the annexed territories, the collection of topographical data, and the eventual production of new maps. (…) she successfully avoids the pitfall of binary thinking in which European and native views of space are diametrically opposed.”East Asian Science, Technology, and Medicine, no.50, 2019, 184-186.“Marie de Rugy’s book distinguishes itself by its analysis of the way Europeans related to colonised peoples and knowledge.”IRSEM - Institute for Strategic Research (Newsletter Oct 2018)“A strong point is the methodological choice to “cross-examine” imperial systems (“croiser les différents systèmes impériaux”), that is, to systematically and critically conduct a comparative study of the British and French colonial worlds, with a focus on a wide range ofdynamics, in particular the circulation of knowledge and practices.”East Asian Science, Technology, and Medicine, no.50, 2019, 184-186.“Intensive and critical research has produced a particularly solid study, which moreover offers a great deal of inspiration for similar research about other colonial settings.” East Asian Science, Technology, and Medicine, no.50, 2019, 184-186.“Aux confins des empires gives a new perspective to borderland studies in Southeast Asia.”IRSEM - Institute for Strategic Research (Newsletter Oct 2018)“The book allows readers to get to the very root of the current hierarchy between margins and centres in Burma, Laos and Vietnam.”IRSEM - Institute for Strategic Research (Newsletter Oct 2018)"One of the book’s strengths is its coverage of indigenous Southeast Asian mapping. In particular, de Rugy spotlights Vietnam’s strong mapping tradition, a subject that has received little attention in the West. The book is handsomely produced, with a generous number of sharp, color images of maps, many of which were previously unknown. It will be a welcome addition to many libraries." – Harold Meinheit, in: Washington Map Society, Winter 2022/23, p.43
