Presidential library
In the United States, the presidential library system is a nationwide network of 13 libraries (with a fourteenth in progress) administered by the Office of Presidential Libraries, which is part of the National Archives and Records Administration (NARA). These are repositories for preserving and making available the papers, records, collections and other historical materials of every president of the United States from Herbert Hoover (31st president, 1929–1933) to George W. Bush (43rd president, 2001–2009). In addition to the library services, museum exhibitions concerning the presidency are displayed.
While not officially sanctioned and maintained by the NARA, libraries have also been organized for several presidents who preceded Hoover and the official start of the Presidential Library Office. The library planned for Barack Obama (44th president, 2009–2017) will partner with the NARA in a "new model", digitizing and making available documents, but without NARA running a new separate facility.
Although recognized as having historical significance, before the mid-20th century presidential papers and effects were generally understood to be the private property of the president. Franklin D. Roosevelt (32nd president, 1933–1945) proposed to leave his papers to the public in a building donated by him on his Hyde Park estate. Since then a series of laws established the public keeping of documents and the presidential library system.
The sites are sometimes referred to as a presidential center.
