"Vanishing Act: The Disappearance of Over 2 Million Research Papers Online"

A study of over seven million digital publications found that more than two million articles with active DOIs were not properly archived, highlighting the failure of systems to preserve papers online. This poses a significant challenge to the long-term sustainability of the research ecosystem, as the inability to verify past research could lead to a reliance on blind faith. The study suggests measures to improve digital preservation, including stronger requirements at DOI registration agencies and better education and awareness among publishers and researchers.
