Welcome
For over 100 years, the Hoover Institution Library & Archives has served as a platform for a vibrant community of scholars and a broad public interested in the meaning and role of history. We collect, preserve, describe and make available collections for research and discovery.
Our collections contain the most important materials on war, revolution, and peace and social, political, and economic change in the modern era. We preserve records of enduring value through proactive care and conservation practices to maintain long term access. Access to our collections for research and scholarship (onsite and online) is free to the public. We build connections to our collections by sparking curiosity and we welcome audiences to explore and learn what the Library & Archives has to offer.
