Library, archive centre and museum at the same time, the mission of La contemporaine is to support research. It provides the scientific community with reference collections and primary documents on the history of the 20th and 21st centuries (press, private archives, photographs, posters, press drawings, etc.) and contributes to the dissemination of research results through its publications. La contemporaine is an active member of CollEx-Persée, a national documentary network of excellence in higher education. The institution provides documentary services to research teams using all its collections, which are also labelled as excellence funds. The library is also part of the Labex "Les passés dans le présent" (Ref. ANR: ANR-11-LABX-0026-01). The blog of La contemporaine gives an overview of the scientific and editorial activities of the institution and its partners.
