Resumo:

In Brazil – a plurilingual country with more than two hundred million Portuguese speakers – sociolinguistic diversity is a cultural heritage that, although documented in some linguistic data collections, lacks documentation via nationally defined parameters for the constitution of memory collections. Collections of this heterogeneous heritage can be explored in teaching (inter)actions in the contexto of mother language and non-mother language, in other discursive actions related to translation, interpretation, subtitling, dubbing, as well as in other areas of knowledge. Aware of the potential of this heritage, six researchers from ANPOLL’s Sociolinguistics WG178 d esigned a p roject for a n ational d igital r epository for cataloging and/or bringing together existing Brazilian collections and those to be built: the Platform for Brazilian Linguistic Diversity. This chapter aims to provide the reader with information about Portuguese speaking and writing data collections and this project, that is being developed by Brazilian Linguistics Association (ABRALIN), and then to contribute to a work with Portuguese that promotes attention and respect for linguistic and sociocultural diversity, for the ways of life of the population in Brazil.
