I am writing a formal research paper (for a competition called National History Day), using the Chicago citation style.
I am using as a source this article. I would like to quote/reference the letter pictured in the article, and also reference some of the article surrounding it. I must sort my sources as primary or secondary. Which is this article? (I know the letter is a primary source.) Also, should I cite the letter and the article separately, or together?
Thanks; any help would be appreciated.
