The use of interviews and the creation of oral resources have become standard practices among historians of education. They also frequently draw on the resources created by the oral archives programme of the Service d'histoire de l'éducation, funded by the Institut national de recherche pédagogique in the 1990s, in a context conducive to large-scale collective surveys and institutional heritage collections. After the golden age of collecting, the time has now come for these archives to be exploited and analysed on a secondary basis by researchers who did not produce them. By revisiting the history of this collection and its uses, this dossier explores the relevance of these questions today and confronts the diversity of research practices and disciplinary as well as archival perspectives. Born of a collective reflection on the role of interviews in historical writing and educational research, it also seeks to support archiving practices within individual and collective research projects. By addressing the methodological, legal, and ethical issues related to the patrimonialization of oral sources, this issue invites the scholarly community to envision an open and shared archival hub dedicated to the history of education.
