Grand dictionnaire universel du XIXe siècle

The Grand dictionnaire universel du XIXe siècle (Great Universal Dictionary of the 19th Century), often called the Grand Larousse du dix-neuvième, is a French encyclopedic dictionary. It was planned, directed, published, and to a substantial degree written by Pierre Larousse, though he also relied on anonymous fellow contributors and though he died in 1875, before its completion. The publication of the Grand dictionnaire universel in 15 volumes of 1500 pages extended from 1866 to 1876. Two supplements were published in 1877 and 1890.
