The National Archives and Records Administration (NARA) is the nation's record keeper. Of all documents and materials created in the course of business conducted by the United States Federal government, only 1%-3% are so important for legal or historical reasons that they are kept by us forever.
Those valuable records are preserved and are available to you, whether you want to see if they contain clues about your family’s history, need to prove a veteran’s military service, or are researching an historical topic that interests you.
National Archives is a meta-portal with access to collections of the different locations of the nationwide network of archives facilities https://www.archives.gov/locations/. A full list of RSS Feeds can be found at https://www.archives.gov/social-media/rss-feeds.html
