UNESCO's new handbook is an essential addition to teaching syllabi for all journalism educators, as well as practising journalists and editors who are interested in information, how we share it and how we use it.Written by experts in the fight against disinformation, this handbook explores the very nature of journalism - with modules on why trust matters; thinking critically about how digital technology and social platforms are conduits of the information disorder; fighting back against disinformation and misinformation through media and information literacy; fact-checking 101; social media verification and combatting online abuse.
