The National Archives has a massively awesome listing of resources related to African American history. This listing includes images (there's a great series on African Americans in WWII here:

and documents related to Amistad (here:

I'm trying to find one related to US Latino studies, but the site's awkward to navigate. I have no idea how I found this! :P
