The Verification Handbook provides step-by-step guidelines for journalists and aid workers to verify user-generated content during emergencies by drawing on expertise from leading news organizations, NGOs, technical communities, and the UN. The guidelines emphasize preparing verification processes and standards in advance, developing human sources, communicating with other professionals, and using tools like EXIF readers and Twitter searches while verifying both the source and content of information. The Handbook aims to help separate news from rumors and misinformation by training professionals in verification best practices.
