I have to cite the same reference two times on each footnote on different pages. Suppose footnote note 1 on page 1 is the same reference as footnote 7 on page 4. Should I provide different serial numbers for the footnote or the same?
Can I repeat the same reference twice with different footnote numbers, or should I us the same footnote number for identical references? I cannot write "ibid", as the footnotes are not in sequence.
