The National Archives

DocsTeach is a product of the National Archives education division. Our mission is to engage, educate, and inspire all learners to discover and explore the records of the American people preserved by the National Archives.

The National Archives and Records Administration is the nation's record keeper. We save documents and other materials created in the course of business conducted by the U.S. Federal government that are judged to have continuing value. We hold in trust for the public the Declaration of Independence, the Constitution, and the Bill of Rights — but also the records of ordinary citizens — at our locations around the country.
