The present work initially highlights the importance of studies on the phenomenon of information in the digital environment. It makes considerations about the possibility of interdisciplinary action by professionals in the field of Information and Communication Science, specifically Librarians and Journalists. The critical reflection on the possibilities of these professionals' joint work in the fight against infodemic and misinformation brings as a structural definition the practices of digital culture proposed by the author Dalton Martins, characterized as: informational, communicational, relational and curatorial practices. Within this scope, approximations in the performance of librarians and journalists are presented and based on their specific skills and abilities. It was concluded that, although there are differences in the temporality of performance between both areas, since journalists basically deal with information that needs to be revealed immediately, an interdisciplinary trajectory that involves the librarian in this journalistic context appears to be unfolding as a huge potential for leveraging fact checking actions by making it possible to accurately and reliably back up information sources for the initial stages of the journalists' work, providing greater agility in the production of news
