The most recent issue of Dttp:Documents to the People (Winter 2007) had two very good student papers that used government documents in a major way to tell history. I found them engaging and informative and hope you'll find a copy and read them through:

Space Tourism: These Trips Are Out of this World by Alex Bertea on page 19.

Waterfowl and Wetlands: A History of the Federal Ducks Stamp Program by Marcy Carlson on page 23.

Both Bertea and Carlson are library school students. I'm glad to see LIS students researching well and able to communicate their hours of research that made me care about their subject.
