This volume begins with an overview of Joshua A. Fishman's extensive work and influence in the field of language planning. The other papers link language planning with weighty issues such as politics, ecology, and national development. More specific papers deal with the problems of political and social intricacies of language planning in the European Community, in India, on the African continent, in Israel, Cuba and Quebec. Two papers deal with corpus planning from a lexicological (Yiddish) and terminological point of view.
