From a NARA Announcement:
The National Archives and Records Administration (NARA) today launched the Donald J. Trump Presidential Library website, which provides information on archived White House websites and social media accounts, as well as information on access to the records of the Trump Administration.
Under the Presidential Records Act, the National Archives receives all records of the Trump Administration, which will be preserved in NARA facilities in the Washington, DC, area, and access to those records will be provided through the Donald J. Trump Presidential Library, controlled and administered by the National Archives.
The Trump Library will be part of the National Archives’ Presidential Libraries system, which, under the Presidential Libraries Act, established a system of privately constructed and Federally maintained Presidential Libraries, going back to President Hoover’s administration. NARA’s Presidential Libraries promote understanding of the Presidency and the American experience. They preserve and provide access to historical materials, support research, and create interactive programs and exhibits that educate and inspire.
Regardless of whether a former President decides to build and donate an archival research facility and museum to NARA under the Presidential Libraries Act, the National Archives maintains the collection of Presidential records created by the Presidential administration as a Presidential Library. The Trump Library will be the fifteenth Presidential Library operated by the National Archives.
