Footnotes are added to the bottom of a research paper to show where a fact or other piece of information came from. Footnotes are used in the Chicago writing style the same way in text citations are used in MLA and APA writing styles. For example, if you reference a speech in a research paper, such as a point that was made in the speech or a direct quote, then you need to cite this information. In the Chicago writing style, the speech is cited in a footnote at the bottom of the page where it was referenced.
Create the complete bibliography entry for the speech. The entry needs to be in a specific format: "Name of Speaker, "Title of Speech" (Title of conference/meeting speech was given, Location of speech, Date of speech). A sample entry would look something like, "Barack Obama, "The American Promise" (Democratic National Convention, Denver, Colorado, August 28, 2008).
Place a footnote number after the area of your text where you reference the speech, use information from it or quote it. Your word processing program will allow you to add a footnote number. For example, if this is the first footnote in your paper, you would add a number 1.
Add the footnote for the speech at the bottom of your page. Again, your word processing program will allow you to add a footnote, which is separate from the rest of your text. The first time the speech is referenced, include the entire bibliography reference in the footnote.
Include a separate footnote each additional time the speech is referenced or quoted. Number the footnotes accordingly. At the bottom of the page, add a shortened version of the bibliography entry for each footnote after the first one for the speech. The shortened form includes the author's name. If you're using a paper copy of the speech, also include the page number where the information was found within the speech in the footnote.
