In this photo taken April 16, 2013, a large screen displays images and video of the events and days that followed the 9/11 terrorist attacks as part of an exhibit in the museum area at 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.
