Enter the footnote number first, followed by the president's name. If the speech is found online, enter its name in quotation marks.
Enter the title of the source in italicized text. If the speech was taken from a book, rather than a website, enter the city of publication followed by a colon, the publisher's name followed by a comma, and the date of publication, all in parentheses.
Enter the volume number, if there is one, for online citations. Follow this with the date of address in parenthesis. Next enter the page or pages cited, if the database includes them, preceded by a colon and followed by a comma. Paste in the document URL and conclude with the date of access in parenthesis.
Enter the volume number if you're citing from an offline document, as well, followed by a colon and the pages cited. No date is necessary.
Compare your citation to the following example, to see if it's correct:
1. Barack H. Obama, "Message on the Observance of the National Aeronautics and Space Administration's Day of Remembrance," Daily Compilation of Presidential Documents 00061 (January 29, 2010):1, http://www.gpoaccess.gov/presdocs/2010/DCPD-201000061.htm (January 3, 2011).
