Libraries in Paris  Paris, the capital of France, has many of the country's most important libraries. The Bibliothèque nationale de France (BnF; in English "national library of France") operates public libraries in Paris, among them the François-Mitterrand, Richelieu, Louvois, Opéra, and Arsenal. In the 2nd arrondissement, the Bibliothèque Richelieu is to a design by Henri Labrouste with nine domes; it opened in 1868. There are three public libraries in the 4th arrondissement. The Bibliothèque Forney, in the Le Marais district, is dedicated to the decorative arts; the Arsenal Library occupies a former military building, and has a large collection on French literature; and the Bibliothèque historique de la ville de Paris, also in Le Marais, contains the Paris historical research service.
