The Nouveau Larousse illustré (New Larousse Illustrated) was an illustrated French language encyclopedia published by Éditions Larousse between 1897 and 1904, in 7 volumes and a supplement. It was essentially a scaled-down version of the Grand dictionnaire universel du XIXe siècle (Great universal dictionary of the 19th century) of Pierre Larousse, but updated and written in a more neutral, scientific style under the editorship of Claude Augé (1854−1924).
The encyclopedia consisted of 7,600 pages containing 237,000 articles, with 49,000 black and white illustrations, over 500 maps and 89 colour plates.
