Special Collections at the Chinese University of Hong Kong Library has a small but important collection of early Western rare books on China. They are important records of the customs, society, politics and economy in China, as well as the early Sino-Western encounters and exchanges. Most of them were written by missionaries in the 16th and 17th centuries. The name of Mendoza, Ricci, Le Comte, and Du Halde are synonymous with any early Western studies of Chinese culture and were used for centuries as reference for those interested in the Chinese Empire and its history.
