The Library has extensive collections of French material, ranging from the history of the early Franks to modern France. There are strong local history holdings, as well as national material, making the IHR unrivalled as a source for French local history in Britain. The IHR's collections focus on primary sources, with supplementary guides, bibliographies, reference works and periodicals.
There are strong collections of chronicles, cartularies, editions of letters, political, legal and biographical works. Although there are extensive holdings on all periods of French history, the nineteenth century is particularly well-represented, thanks to a bequest from Vincent Wright.
