OurDocuments.gov might possibly be the coolest government web site I've ever seen. Here is what the editors at Yahoo! had to say about it:
In a time when instant messaging and email correspondence rule communications, this site preserves the United State's 100 most important and timeless documents. The elegant interface allows you to zoom in close to examine the handwritten calligraphy found on the Constitution, Articles of the Confederation, and Treaty of Paris. Relive high-school history class as the Treaty of Guadalupe Hidalgo, the Homestead Act, and the Tonkin Gulf Resolution leap from the chronological list of 100 Milestone Documents. Drafted long before the days of keyboards, these papers are not only a reflection of American milestones, but are also a testament to the craft of language. This is one paper trail you definitely want to follow.
