Œuvres complètes de Voltaire: Correspondance (années 1711-1776, nos. 1-9750) 1880-82

This monumental collection was published between 1880 and 1882 as part of the definitive 'Œuvres complètes de Voltaire' edited by Louis Moland. Produced by the publisher Garnier Frères in Paris, this effort aimed to consolidate Voltaire’s vast intellectual output during the height of the French Third Republic's interest in Enlightenment history. The correspondence volumes remain a cornerstone of 19th-century scholarship, intended to provide a comprehensive record of the philosopher's interactions with his peers and the political elite of his era.

The editorial work was guided by Moland, who sought to organize and annotate the letters to establish a reliable baseline for academic study. The design follows the rigorous, scholarly aesthetic of late 19th-century French publishing, emphasizing clarity and archival utility. While the individual letters date back to the 18th century, the 1880-82 collection is celebrated for its systematic approach to indexing and its role in preserving the epistolary legacy of a central figure in Western philosophical thought.
