This paper proposes an overview of practices ensuring the gradual transition of printed archaeological journals, already internationalised, to new models of online scientific publishing. It also examines the economic and organisational means that guarantee the sustainability of these models. Our two research units, the Pôle éditorial of the Maison des Sciences de l’Homme Mondes and the team Archéologie du monde grec et systèmes d’information of the ArScAn équipe, are both based in the campus of Nanterre, and collaborative discussions between the numerous professionals based there give us a precious glimpse at the evolutions of practices in terms of data management and publication, in a context of Open Science where scholarly publications and data tend to be open more widely and faster.
