This paper argues that Serbian as the language of Diaspora represents a phenomenon of interest of a number of disciplines qualified as humanities and social sciences, including philology and linguistics. It examines how Serbian as heritage language has been explored since 1968 to the day and it reviews mainly the work of the authors from the territory of Serbia, as well as those from the ex-Yugoslav republics that have enabled the maintenance of continuity in this stream of research. An exception is made for a brief review of the research on Serbo-Croatian as the language of migration conducted by a research team at the Lund University in Sweden in the 1980s. In the corpus, particularly significant are the publications that explore different linguistic, psycholinguistic, sociolinguistic, and philological aspects of the Serbian language in Diaspora, as well as those that are concerned with the education in Serbian as heritage language. In spite of their importance, we note a remarkable scarcity of the research for the lapse of almost four decades and we note that these phenomena can be thoroughly and systematically explored only from an interdisciplinary and transdisciplinary perspective.
