The Archives and History Department's mission is to reconstruct the history of the OSE, an association created in 1912 in Saint Petersburg and established in France since the early 1930s. One of the main missions of the service is to accompany people, mainly survivors and/or their families or relatives, in their research and procedures, particularly with a view to having their rights recognised. In addition to its research and support role, the Archives and History Department uses a variety of media to pass on the history of the association during the war and in the post-war period: writing and publishing historical books and articles, designing exhibitions on different aspects of the OSE's history, taking part in conferences and colloquia, digitising children's files and archival documents, enriching the photographic database, assisting in the writing of testimonies and collecting testimonies of hidden children.
