The international exchange of publications has several hundred years of history, beginning in Europe and then spreading to the United States and consequently throughout the globe. It can be said that this kind of exchange provides the bridge necessary for a free exchange between cultures of the world. As international exchange developed, global international• conventions were established twice: in 1886, with the complete Brussels Conventions, and in 1958, with the ratification of UNESCO's Convention Concerningng the International Exchange of Publications and Convention Concerning the Exchange of Official Publications and Government Documents Between States. Nevertheless, for those involved the very word "exchange" often carries the feeling of being at a loss because of the large number of situations in which many publications are sent but few received—the "unequal exchange." Weighing all the domestic deficiencies of research in this area, this paper employs the study of the history and conventions of international exchange to clarify the practical significance and theory of international exchange. In addition to eliminating uncertainties about the meaning of "international exchange of publications," this paper undertakes to encourage the further development of such exchange in the R.O.C.
