A while back I did a page for an interdisciplinary unit with 8th grade
social studies. We were going to do Kruger style photo collage with text.
Below is my updated page:

This is not a comprehensive list of US history resources -- but is enough
just to get a "taste". At the bottom of the page are resources for images in
Public Domain -- several links pages included with resources I don't have
listed. If you have a good source for US History - please post to the list
and I will add to my page.
