Those are great resources; thank you all. Although it is not stictly an American history resource I find a lot of interesting things in The WWI Document Acrhive:http://www.lib.byu.edu/~rdh/wwi/. It's alway enjoyable just to browse through that site.

gogov.com has a link to a pretty good collection of U.S. documents. I can't remember the link name but you can find it by clicking on the flag.

I utilize the Avalon Project. I have it to be very user friendly.
