When was your speech (or artifact) first presented? One of the best places to get a sense of the time period is through newspapers. UNLV Libraries has a wide selection of newspaper databases going back centuries through today.
You will be able to find a wide variety of rhetorical analyses & criticisms, along with a wide variety of resources about the speaker on the Library's QuickSearch (on the home page), in the library catalog, and in UNLV Libraries databases such as Communication & Mass Media Complete, Communication Studies, ComAbstracts, and JSTOR.
You may also want to try Google Scholar to expand your search to a wider variety of disciplines at once.
Considering this semester's theme is public discourse in the Las Vegas Valley, you'll become acquainted with UNLV's Special Collections, located in the 3rd floor of Lied Library.
