The letter is a primary source, as you already know. This is the _actual artifact_, the letter the young woman received from NASA. The article about the history of these events is a secondary source; it's not a record of the events itself but a description. (It might actually be a tertiary source, but you could make the case for secondary.) [This article](http://tuskegee.libguides.com/c.php?g=546110&p=3780244) explains more about primary, secondary, and tertiary sources. It's not part of CMOS but appears to be from a university that uses CMOS as its standard. If you are using the article only to provide access to the letter, then you cite the letter while crediting the publication: > Lloyd, Jr., O. B., O. B. Lloyd, Jr. to Linda Halpern, March 13, 1962, in [... cite article here] See "a letter found on a website" in [these Chicago citation guidelines](http://library.menloschool.org/chicago/letter). If you are also using the article in other ways, and not just as your source for the letter, then cite the article itself where you use it.
