On fake news, gatekeepers and LIS professionals: the finger or the moon?

Purpose The purpose of this paper is to reflect on the meaning of fake news in the digital age and on the debate on disinformation in scholarly literature, in the light of the ethics of library and information profession. Design/methodology/approach Revision of a keynote address at the BOCATSSS2020 conference, this paper offers an overview of current literature comparing it with a moment in the past that was crucial for information: post-Second World War time, when Wiener (1948) founded cybernetics and C.P. Snow advocated for “The two cultures” (1959). Findings The complex issue demands a multi-disciplinary approach: there is not one solution, and some approaches risk limiting the freedom of expression, yet countering the phenomenon is a moral obligation for library and information science professionals. Originality/value Comparing the present digital revolution with the past, this paper opens questions on the ethical commitment of information professionals.
