#SOSRioDoce e #1AnoDeLamaELuta: um estudo sobre a recuperação de documentos nato-digitais

The work aims to identify the implications of network use as a repository of born-digital memories usable in historiographic production and thus to stimulate the use of these memories as a historical source. For this purpose, we adopted an exploratory approach retrieving information about Mariana disaster using the hashtags #SOSRioDoce and #1AnoDeLamaELuta as keywords. Through the tests performed, it was possible to identify and systematize variables that interfere with data collection process. Methodology design was especially detailed throughout the work in order to give visibility to the constitution of borndigital documentary corpus strategy for purposes of historical research. The documentary collection about Mariana disaster produced on the basis of the tags gave rise to a source file made available to the reader.
