Renovations
On April 23, 2007, the permanent exhibit closed for complete renovation (though the temporary exhibit gallery remained open, hosting the popular "Traveling White House in Miniature" exhibit). Since it reopened on November 10, 2007, the permanent exhibit features (like many other presidential libraries), a replica of the Oval Office; unlike those presidential libraries, visitors will be able to fully enter the replica, sit behind the president's desk, and have a souvenir photo taken.
