The Siku Quanshu, sometimes translated as the Complete Library of the Four Treasuries, was one of the most ambitious intellectual projects of the Qing dynasty. Initiated by imperial command in 1772, the project sought to evaluate, edit, and reproduce the finest Chinese writings in the four traditional categories: Confucian classics, histories, philosophy, and literature. The final products, created over a twenty-two year period, were an annotated catalog of some ten thousand titles and seven new manuscript libraries of nearly thirty-six hundred titles.
