Sci-Hub, a challenge for academic and research libraries

Sci-Hub emerged into the field of scientific communication in 2011 as a platform for free access to scientific papers. It is the most popular of the so-called shadow libraries, systems that overcome the limits of legal access to scientific publications, standing apart from the open access movement. Besides from the media coverage that has served to boost its popularity, several studies reveal the impact of Sci-Hub among researchers, who have embraced this initiative. Sci-Hub has revealed new forms of access to scientific information, affecting academic and research libraries that cannot remain on the sidelines. This study addresses the Sci-Hub phenomenon and its implications for academic and research libraries from different points of view, through a bibliographic review and an analysis of examples of action.
