I have cited the same source multiple times on one page of my essay. In my footnotes do I have to list the source each time, or is there a technique to list footnote numbers before the source like "1, 2, 3 2004 website about this" (Ignore the complete wrong naming of source).
When using the Chicago style, the following (from here) may be considered:
The first note for each source should include all relevant information about the source: author’s full name, source title, and facts of publication. If you cite the same source again, the note need only include the surname of the author, a shortened form of the title (if more than four words), and page number(s).
If you cite the same source and page number(s) from a single source two or more times consecutively, the corresponding note should use the word “Ibid.,” an abbreviated form of the Latin ibidem, which means “in the same place.” If you use the same source but a different page number, the corresponding note should use “Ibid.” followed by a comma and the new page number(s).
So, you would cite the sources in brief every time they come after the first full citation. To understand how to shorten the citation, refer here.
