The new "Russia's War in Ukraine" collection seeks to document Russia’s invasion of Ukraine on February 24, 2022 which resulted in a full-scale war after eight years of military conflict between Russian and Ukraine. Content includes news portals (such as Kyiv Independent, Euromaidan Press, and 24tv), digital library or archive websites with important cultural and historical data (e.g. Institute of History Digital Library, Ukrainian Institute of National Memory), government and civil society websites (e.g. Verkhovna Rada of Ukraine, People for UA, Defense UA), documentation of the war and resources for refugees (e.g. Civilian harm in Ukraine, My story of the war in Ukraine, Info Help UA), and social media related to the war (accounts of President Zelensky, Dmitro Kuleba, Vitali Klitschko, Cabinet of Ministers, etc).
The purpose of this project is to make data pertaining to the ongoing war easily available to researchers as well as to preserve important information that could be at risk if Ukraine's internet and digital infrastructure were damaged.
