For a bibliographical study see: M. Tourneux, _Marie Antoinette devant l'histoire. Essai bibliographique_ (2nd ed., Paris, 1901); id. _Bibliogr. de la ville de Paris ..._ (vol. iv. 1906), nos. 20980-21338; also _Bibliogr. de femmes célèbres_ (Turin and Paris, 1892, &c.). The most important material for her life is to be found in her letters and in the correspondence of Mercy-Argenteau, but a large number of forgeries have found their way into certain of the collections, such as those of Paul Vogt d'Hunolstein (_Correspondance inédite de Marie Antoinette_, (3rd ed., Paris, 1864), and F. Feuillet des Conches _Louis XVI., Marie Antoinette et Madame Élisabeth, lettres et documents inédits_ (6 vols., Paris, 1864-1873), while most of the works on Marie Antoinette published before the appearance of Arneth's publications (1865, &c.) are based partly on these forgeries. For a detailed examination of the question of the authenticity of the letters see the introduction to _Lettres de Marie Antoinette. Recueil des lettres authentiques de la reine, publié pour la société d'histoire contemporaine, par M. de la Rocheterie et le marquis de Beaucourt_ (2 vols., Paris, 1895-1896); also A. Geffroy, _Gustave III. et la cour de France_ (2 vols., Paris, 1869), vol. ii., appendix. Of the highest importance are the letters from the archives of Vienna published by Alfred von Arneth and others: A. von Arneth, _Maria Theresia und Marie Antoinette, ihr Briefwechsel_ 1770-1780 (Paris and Vienna, 1865); id., _Marie Antoinette, Joseph II. und Leopold II. ihr Briefwechsel_ (Leipzig, Paris and Vienna, 1866); id. and A. Geffroy, _Correspondance secrète de Marie-Thérèse et du comte de Mercy-Argenteau_ (3 vols., Paris, 1874); id. and J. Flammermont, _Correspondance secrète du comte de Mercy-Argenteau avec Joseph II. et le prince de Kaunitz_ (2 vols., Paris, 1889-1891); for further letters see Comte de Reiset, _Lettres de la reine Marie Antoinette à la landgrave Louise de Hesse-Darmstadt_ (1865); id. _Lettres inédites de Marie Antoinette et de Marie-Clotilde, reine de Sardaigne_ (1877). See also _Correspondance entre le comte de Mirabeau et le comte de la Marck, 1789-1791, recueillie ... par F. de Bacourt_ (3 vols., Paris, 1857), and Baron R. M. de Klinckowström, _Le Comte de Fersen et la cour de France_ (2 vols., Paris, 1877-1878). _Memoirs_: See most contemporary memoirs, e.g. those of the prince de Ligne, Choiseul, Ségur, Bouillé, Dumouriez, &c. Some, such as those of Madame Campan, Weber, Cléry, Mme de Tourzel, are prejudiced in her favour; others, such as those of Besenval, Lauzun, Soulavie, are equally prejudiced against her. M. Tourneux (_op. cit._) discusses the authenticity of the memoirs of Tilly, Cléry, Lauzun, &c. The chief of these memoirs are: Mme Campan, _Mémoires sur la vie privée de Marie Antoinette_ (5th ed., 2 vols., Paris, 1823, Eng. trans. 1887), the inaccuracy of which
