Cultural exchange between China and the West reached its first peak of modern times during the late Ming and early Ch'ing dynasties., with the arrival of Christian missionaries in China with Western scientific publications. This chapter of history offers three missionaries worth discussing as representatives of this kind of book exchange. The first is Matteo Ricci, the first person to effect cultural exchange between China and the West, a contribution of enormous proportions. The second is Nicolas Trigault, who in 1619 brought over 7,000 volumes into China. The third is Joachim Bouvet, who. in 1697 donated in the name of emperor K'ang-Hsi 312 volumes in forty-five sets under twenty-two different titles to the King of France, Louis XIV, volumes that are still held today in the National Library of France. This paper addresses the exchange of publications between China and the West in four parts: an account of the arrival of Jesuits in China; an introduction to Ricci's importation of Western books, and to his own writings and translations; an account of the importation of books by Trigault, as well as of their number and contents; and an investigation into the legitimacy of' Bouvet's donation in the name of emperor K'ang-Hsi.
