The Ljubljana seminar, whose background and working papers are presented in this volume, was an outcome of the United Nations' consideration of the problems of ethnic and linguistic minorities. The twenty-five papers cover topics such as the study of multinational societies; the protection of minorities and minority rights in Yugoslavia, Czechoslovakia, Austria, the Soviet Union, India, Africa, Southeast Asia, Israel, Britain, and the Caribbean; cultural diversity; and immigrant problems. Chapters 1-3 are background papers, commissioned by the United Nations Secretariat in preparation for the seminar. Chapters 4-23 are working papers, contributed by the participants and presented in regional groups, starting with Central Europe and going on to include Asia, Africa, and North America. (Author/CLK)
