The National Archives and Records Administration (NARA) maintains 12 presidential libraries under its authority. These presidential libraries serve as museums for the partisans of the men who’ve served as president going back Herbert Hoover, as well as sites of serious scholarly inquiry.

Did you know each presidential library has its own page in our ArchivesWiki? We invite presidential scholars and others who have done research in these libraries to contribute to this ongoing project:
