"A more complex ordering system appears in what is known as the largest encyclopedia ever printed: the Qinding Gujin Tushu Jicheng, or Great Illustrated Imperial Encyclopedia of Past and Present Times, of 1726, a gigantic biographical library divided into more than ten thousand sections. The work was attributed to Jiang Tingxi, a court proofreader who used wooden blocks with cut-out pictures and movable characters specially designed for the enterprise. Each section of the encyclopedia covers one specific realm of human concern, such as Science or Travel, and is divided into subsections containing biographical entries. The section on Human Relations, for instance, lists the biographies of thousands of men and women according to their occupation or position in society, among them sages, slaves, playboys, tyrants, doctors, calligraphers, supernatural beings, great drinkers, notable archers and widows who did not marry again."
