George W Bush's presidential library, museum and policy centre has opened in Dallas, Texas.
All modern-day presidents have been honoured with such libraries in their home states, including Richard Nixon, whose library draws about 100,000 visitors a year with its exhibits and research opportunities.
The complex, which opened in 1991, is built around the thirty-seventh president’s childhood home in southern California.
Nixon is best remembered for the Watergate scandal, an illegal spying operation on his political enemies, and the cover-up that followed, events extensively dealt with in the library’s exhibits.
