The main theoretical contributions used by the research took into account the theme discussed in the article. About cyberculture and social media, based on authors such as Lévy (2010), Lemos (2013) and Recuero (2010) and cultural action based on Coelho (2001), Milanesi (2003) and Barros (2010). Method: The applied methodology included documentary analysis. Along with the documentary analysis of SisEB’s Facebook, content analysis was also carried out, according to Bardin (1977), to verify whether the contents published in this network are related to cultural action. Results: The results point to the first inferences that SisEB publishes more informational content type and dissemination of its activities than the promotion of cultural action itself. Conclusion: Such activities can contribute to the spheres of cultural action, according to Coelho (2001), to become a reality.porAcesso AbertoMídias sociaisBiblioteca públicaCiberculturaAção culturalSocial mediaPublic librariesCybercultureCultural actionArtigo10.5380/atoz.v10i1.76615
