[Tex/LaTex] How to refer to same footnote twice in REVTeX

bibliographiesbibtexcross-referencingfootnotesrevtex

I am using REVTeX 4.1 with BibTeX for references. The author guidelines for a journal state:

Authors should ensure that the journal article contains a reference in
the reference list as follows:

  • See Supplemental Material at [URL will be inserted by publisher] for
    [give brief description of material].

I used the \footnote command to achieve this, as it produces extra entries in the references section by default.

I would like to refer to the same Supplemental Material "reference" more than once. How can I achieve this?

Minimal example. In the real document I do have a .bib file too, not included here.

% proba.tex
\documentclass[footinbib]{revtex4-1}

\begin{document}
Some text here \footnote{Supplemental Material reference}. % produces ref. [1]

I would like to refer to the same Supplemental Material again here. % refer to [1] here somehow
\end{document}

Note that BibTeX does need to be run for this minimal example to work, according to the REVTeX documentation, despite no .bib file being present here.

pdflatex proba
bibtex proba
pdflatex proba
pdflatex proba

Perhaps the solution is not to use \footnote for this purpose. What should I use in that case?

Best Answer

Each \footnote under your document setup produces a bibliography key of the form NoteX where X is the regular footnote number. So, in your case, \cite{Note1} would reference the first footnote citation, while (say) \cite{Note17} would reference a citation in the footnotes corresponding to footnote number 17.

Here's a minimal example explaining its usage:

enter image description here

\documentclass[footinbib]{revtex4-1}

\begin{document}
Some text here \footnote{Supplemental Material reference}, \setcounter{footnote}{16}\footnote{something else}.

I would like to refer to the same Supplemental Material again here \cite{Note1}, \cite{Note17}.
\end{document}
