I tell Harry Middleton [the director of the LBJ Presidential Library] that I heard a rumor that in the initial exhibition at the LBJ library, there was little or no representation of Vietnam and that the president himself came to the library and insisted that that part of the exhibition should be beefed up.Sarah Vowell, The Partly Cloudy Patriot (New York: Simon & Schuster, 2002), p. 24
Middleton nods. "To a certain extent that's true. There was a representation of Vietnam. But nothing that showed the controversy of Vietnam. And when President Johnson walked through the library just before it was to open, one of the things that he commented on was that the library did not indicate how contentious that time was. He said to me, 'That was a very controversial period. We've got to make sure that people know that we understand that.' He said to me, 'I don't want another damn credibility gap.'"
