The Terena entry was elaborated by the anthropologists Maria Elisa Ladeira and Gilberto Azanha, of the Center of Service for the Indigenous Peoples(CTI), based on anthropological and linguistic research which they have undertaken with the group. Ladeira’s doctoral thesis was entitled “A Socio-lingusitic Analysis among a Terena group”, Program of Social Anthropology of the University of São Paulo, in 2001. Azanha is responsible for the technical group 553/FUNAI, which had, as its mission, “to do preliminary surveys for the purpose of restudying the borders of the Cachoeirinha, Taunay and Buriti Indigenous Lands” (Azanha 2000).

Besides the authors of this entry, the Terena have been studied by the anthropologist Roberto Cardoso de Oliveira, whose work is a reference point for the study of these people. His principal books on the Terena are: Urbanization and Tribalism: the integration of the Terena Indians into a class society (Zahar Editores, 1968) and From Indian to Bugre: the process of assimilation of the Terena (2ª ed. Francisco Alves, 1976). In this entry there are numerous references to the work of Cardoso de Oliveira.
