BARBIER, ANTOINE ALEXANDRE French librarian and bibliographer, became librarian successively to the Directory, to the Conseil d'Etat, and in 1807 to Napoleon, for whom he carried out a number of commissions. He had a share in the foundation of the libraries of the Louvre, of Fon tainebleau, of Compiegne and Saint-Cloud ; under Louis XVIII. he became administrator of the king's private libraries, hut in 1822 he was deprived of all his offices.
