Abstract

Analysis of post-truth and, especially, of the underlying phenomenon of fake news in terms of evaluation and ability to identify reliable sources, and the role of libraries as infomediaries. The main international initiatives proposed by organizations such as IFLA and ALA are discussed. According to the bibliography reviewed, two main kinds of action are proposed: inclusion in informational literacy programs, mainly extending media literacy so that they are oriented from a more civic perspective; and content curation, making thematic guides that are a point of information about the phenomenon and its tools to verify facts. Libraries should act also as a gateway to disseminate information of the library’s collection.
