In this photo taken April 16, 2013, letters written from around the world and sent to the White House offering thoughts and prayers after the 9/11 attacks are displayed in the museum area of the George W. Bush Presidential Library and Museum in Dallas. The museum uses everything from news clips to interactive screens to artifacts to tell the story of Bush’s eight years in office. The George W. Bush Presidential Center, which includes the library and museum along with 43rd president’s policy institute, will be dedicated Thursday on the campus of Southern Methodist University in Dallas.
