The RUSI Library of Military History is a world-leading resource, dedicated to developing our knowledge of war and shaping theoretical approaches to modern military thinking.

An integral part of RUSI, the Library is home to over 16,000 volumes which form a unique and ever-growing repository of books. Our catalogue contains a broad range of military history texts, though our largest collections are of eighteenth, nineteenth and twentieth century military affairs.

The current library site was conceived by Sir Aston Webb and opened in 1895. The spacious and accommodating design makes the library a perfect place for holding lectures and events, or for individual studies and small groups: it serves as a real hub for RUSI, where academics and enthusiasts can explore current and previous thinking on military strategy. The library is fully accessible to both members and non-members, though members have the added privilege of borrowing books at any time.
