Migration, and Language" (1965) elaborates on the role of linguae francae in urbanization and migration, especially in West Africa. As well, the importance of sociolinguistics as an explanatory component in language contact situations is underscored. "The History and Present Status of African Linguistic Studies" (1965) contains an excellent account of the early (seventeenth century to 1910) history of studies of African languages. The article concludes with an inventory of topics and problems which require research, emphasizing those which might form a basis for intelligent language policy formulation. A more thorough treatment of this latter issue appears in "Sociolinguistic Research in Africa" (with Jack Berry; 1966). In this article, an outline is presented of the more important topics within the area of language and social contexts, and suggestions are made as to how sociolinguistic research might proceed. Similar statements regarding sociolinguistics are found in "Interdisciplinary Perspectives in African Linguistic Research" (1966), but Greenberg also discusses the importance of linguistics for the study of culture history, psycholinguistics, and literature.
