This series of international conferences, inaugurated in Ottawa in 1978, has since taken place alternately in Europe (Lille, Trier, Galway, Oxford, Paris, Potsdam, Saint Petersburg, Vila Real) and in the Americas (Ottawa, Princeton, Washington, São Paulo & Campinas and Urbana-Champaign).
It is the most important platform for researchers working on the history of the language sciences, a field that is still expanding as can be attested by the number of scientific societies and the establishment of several specialized journals on the history of the language sciences.
