New Advances in the History of Archaeology presents the papers from three sessions organised by the History of Archaeology Scientific Commission at the 18th UISPP World Congress (Paris, June 2018). The first session, From stratigraphy to stratigraphic excavation in pre- and protohistoric archaeology organised by Massimo Tarantini and Alessandro Guidi, reviews the development of stratigraphical methods in archaeology in many European countries. The second session, Epistemology, History and Philosophy of Science: Interdisciplinary Perspectives on the History of Archaeology, organised by Sophie A. de Beaune and Oscar Moro Abadia, is characterised by different examples of intersections between archaeology and other disciplines like history and the philosophy of science. Finally, four papers discuss the development of different types of interdisciplinarity in Europe and South America. These were presented in the third session, Archaeology and interdisciplinarity, from the 19th century to present-day research, organized by Laura Coltofean, Géraldine. Delley, Margarita Díaz-Andreu and Marc-Antoine Kaeser.
