1. Type “Sitting Bull autograph card” in the search box, using the quotation marks. Click the link and read the description. What did you learn about Sitting Bull? He toured with Buffalo Bill. I didn't know that. And that I clicked on Cornell University Library and found myself on their site with their address and hours, etc. Very nice.

2. Do a search of your own. What results did you get? What institutions have the materials? What other observations can you make about this resource?
I put in my maiden name and found two genealogies from Wisconsin Historical Society once of which might be my great, great grandfather on my dad's side. He came from Ireland about 1828.
Looks like a great site to do research on genealogies.
