# Reference different places to the same footnote

For example, I want to make footnotes both at Sentence 1 and Sentence 2 (which are on the same page) to the same footnote. Wikipedia's "References" have this effect.

• You might also want to look at the endnotes package. It places all footnotes at the end of the document. – Martin Scharrer Nov 16 '11 at 11:46

• Perhaps you would like to switch to numbered (and footnoted) referencing style, using BibLaTeX? – Lyndon White May 27 '15 at 4:36

You could do this (tested in article and amsart):

Text with first footnote\footnote{\label{note1}This is the labeled footnote}
and more text with a second footnote\footnote{here}.

In this new paragraph we have a reference to the first
footnote\footnotemark[\ref{note1}].


The result will be

Edit: Further testing reveals, that the above solution fails when footnotes are numbered with anything other regular numbers. This is due to the fact, that the argument to \footnotemark is the value of a counter. Placing

\makeatletter
\newcommand\footnoteref[1]{\protected@xdef\@thefnmark{\ref{#1}}\@footnotemark}
\makeatother


in the preamble will allow us to mend the above example allowing any numbering of the footnotes.

Text with first footnote\footnote{\label{note1}This is the labeled footnote}
and more text with a second footnote\footnote{here}.

In this a paragraph we have a reference to the first footnote\footnoteref{note1}.


Edit 2: This will cause a problem when using hyperref where the link created by the \footnoterefmacro points to the previous footnote and not to the referenced footnote. Using the package cleveref as in this answer seems to be the perfect fit.

• Thanks spet! But when I add \usepackage[pdftex]{hyperref} to the preamble, the red square of the last footnote is not displayed properly. Do you mind giving some hints? – Covi Nov 16 '11 at 13:02
• @Covi: I'm not all that familiar with the internals of hyperref but I suspect that the problem is, that the link is constructed from the value of the footnote counter and not the value associated with the label given to \footnoteref. I think we need an expert on the subject to solve this :) – spet Nov 16 '11 at 13:17
• @Covi: DO NOT provide a driver to hyperref. It is smart enough to do this by itself, and a wrong driver will cause a lot of trouble. – Martin Scharrer Nov 16 '11 at 13:41
• @Covi: Have a look at Multiple references to the same footnote with hyperref support - is there a better solution?. It looks like it would be helpful. – Martin Scharrer Nov 16 '11 at 13:42
• This second answer to @MartinScharrer's link works for me. I will edit the above answer. – spet Nov 16 '11 at 20:44

Have you ever seen that in a book? Probably not. Because: Two footnotemarks numbered with e.g. an "8" raise the question whether it is a typo. But your readers can not come and ask you, if you really meant to do it this way.

Please, if you'd like to refer to the same text, make a footnote saying (maybe in better English than mine):

¹ Long sentence at: Wallace, Infinite Jest, p. 1234.

² See footnote 1.

What you'd like to do is against an old and sensible tradition. It neither an excuse that a part of Wikipedia does it, nor that it is technically possible.

• In general I have the same opinion about this as you, but for example this is really common for affiliations: Smith, A. ^1, Miller, B. ^2, Williams, C. ^1 --- 1 Institute for Research on Footnotes, A-town. 2 Footnotes Reasearch & Developement, Inc., B-town. (especially if there is a list of 20 authors with 14 affiliations, and some of the authors have even more than one affiliation.) – Stephen Mar 12 '12 at 17:12
• @DerMike In the answer above you find \labe{footn:on-something}. Just put that (not tested, though) in the footnote you'd like make a reference to. – Keks Dose Nov 7 '12 at 11:42
• Another application is footnote in tables, as mandated e.g. in the Physical Review style. It can help distinguish the way different values are obtained while not obstructing the main purpose of the table (comparing them). – Frédéric Grosshans May 11 '18 at 8:01
• Imagine you have a table with many rows, and you want to point out that several cell entries are similar in some way (e.g. are all pain killers, or are all diabetes medication). Then you use a footnote "pain killers", to which all footmarks 1 point, a footnote "diabetes medication", to which all footmarks 2 point. Just because you can't imagine a use case, it doesn't mean that one does not exist. – Ataxias Oct 19 '19 at 6:32
• @KeksDose The title is "Reference different places to the same footnote", so very general. The question starts with "For example, ...", so it's just an example use case. I agree with you that the particular example was not a good use case of the technical feature, but a good answer would answer how the objective can be technically achieved, and then comment that "however, this example is not a good use case". Don't forget that people searching for this feature would land on this page, and they may have legitimate use cases in mind. – Ataxias Oct 19 '19 at 18:42

I'm a bit surprised that noone mentioned KOMA-Script's \footref before. The KOMA-Script manual also has an example where multiple reference to the same footnote could make sense:

Maybe you have to mark each trade name with a footnote which states that it is a registered trade name.

One could think of other similar cases…

\documentclass{scrartcl}
\begin{document}

Company SplishSplash\footnote{This is a registered trade name.
All rights are reserved.\label{refnote}}
produces not only SplishPlump\footref{refnote}
but also SplishPlash\footref{refnote}.

\end{document}


This functionality can be used with the standard classes by using scrextend:

\documentclass{article}
\usepackage{scrextend}
\begin{document}

Company SplishSplash\footnote{This is a registered trade name.
All rights are reserved.\label{refnote}}
produces not only SplishPlump\footref{refnote}
but also SplishPlash\footref{refnote}.

\end{document}


The documentclass memoir already has its own \footref:

\documentclass{memoir}
\begin{document}

Company SplishSplash\footnote{This is a registered trade name.
All rights are reserved.\label{refnote}}
produces not only SplishPlump\footref{refnote}
but also SplishPlash\footref{refnote}.

\end{document}


And for completeness' sake: the footmisc package also defines \footref:

\documentclass{article}
\usepackage{footmisc}
\begin{document}

Company SplishSplash\footnote{This is a registered trade name.
All rights are reserved.\label{refnote}}
produces not only SplishPlump\footref{refnote}
but also SplishPlash\footref{refnote}.

\end{document}

• \footref{refnote} worked perfect for me, even when inside a table! – WarrenFaith Apr 8 '13 at 22:31
• footmisc package also has \footref – Fran Aug 25 '15 at 16:02
• When I run this the repeated notes show a double questions mark instead of the footnote number. – Keivan Oct 31 '16 at 3:48
• @Keivan you a) need a \label in the right place and b) must at least compile twice! – cgnieder Oct 31 '16 at 6:32
• This appears to conflict with href. – EL_DON Jan 24 '18 at 21:57

I found a rather simple way to do this. Just place a label inside the first footnote, and where you want your second reference you make insert a cross reference to that label in superscript, to make it look like a footnote

    line1 \footnote{text bla bla \label{xx}}
line2 \textsuperscript{\ref{xx}}

• This seems to be a slight variation of this answer. – lockstep Jun 4 '13 at 12:54
• This becomes a problem when there's a page break between the two lines. – rmp251 May 13 '14 at 15:19
• \textsuperscript doesn't match the font of \footnote in general, although at least this answer doesn't conflict with other packages. – EL_DON Jan 24 '18 at 22:00

The Wikibook LaTeX provides an answer to this question:

To make multiple references to the same footnote, you can use the following syntax:

Text that has a footnote\footnote{This is the footnote} looks like this.
Later text referring to same footnote\footnotemark[\value{footnote}] uses
the other command.


If you need hyperref support, use instead:

Text that has a footnote\footnote{This is the footnote}
Later text referring to same footnote\footnotemark uses the other command.


Note that these approaches don't work if there are other footnotes between the first reference and any of the other "duplicates".

• This works even within the beamer-class – Murmel Jul 24 '19 at 9:30

The package fixfoot make just that, specially designed for footnotes that appears very often, but in a page-by-page basis. This way the reader never need to go back to read a footnote, but never is printed more than once in the same page.

Each repeated footnote must be pre-declared and invoked with their own custom command (e.g. \repnote) in the preamble or the document environment. Note that duplicates of the footnote appear in the first compilation. You need two compile at least twice. Note also that in next pages the footnote could appear again but with a higher count:

\documentclass{article}
\usepackage[a5paper,paperheight=3.5cm]{geometry}
\usepackage{fixfoot}
\DeclareFixedFootnote{\repnote}{ This is a repated footnote}
\begin{document}
Text with first footnote\repnote\ and more text with a
second normal footnote.\footnote{ This is a single footnote}
Now again the first footnote.\repnote
\newpage
Again the first note \repnote  and another  footnote\footnote{
This is a another footnote}, and finally the fixed footnote\repnote.
\end{document}


If you do not want use \repnote\ to maintain the space between words, you can use the starred version (\DeclareFixedFootnote*) that automatically insert a \xspace (however, the xspace is not loaded automatically with fixfoot (i.e., you will need \usepackage{fixfoot,xspace} in the preamble).

• This doesn't work for me. It just repeats the footnote with a new number. – Keivan Oct 31 '16 at 3:45
• @Keivan You must compile my MWE two times. The first time you will see 6 footnotes, but the second time only the four showed here. – Fran Oct 31 '16 at 3:53
• The first time this appears in text, the footnote mark is A, as it should be for my document. The second time, though, it's a 1. The mark in the footer is an A, as it should be. – EL_DON Jan 24 '18 at 22:04
• @EL_DON With this information and without a minimal working example (MWE) I am afraid that I would have to be psychic to understand your problem. Please first check if some question about footnote marks in this site help you, otherwise post your own question with a MWE to show clearly what are you trying (and stating clearly what is the desired result). – Fran Jan 24 '18 at 23:08
• Just add \renewcommand{\thefootnote}{\Alph{footnote}} to the code in your answer. Only the first instance of \repnote gets the \Alph – EL_DON Jan 25 '18 at 17:08

For beamer, the solution using \footnotemark[\ref{<tag>}] did not work for me. I used \textsuperscript instead.

Text with first footnote\footnote{\label{note1}This is the labeled footnote}
and more text with a second footnote\footnote{here}.

In this a paragraph we have a reference to the first
footnote\textsuperscript{\ref{note1}}.


I stumbled across the same question. Also, for me, \footnotemark did not work. Reason being the Hyperref-Declarations in the Template to be used from University. I actually found a similar workaround as posted above, just without the use of additional usepackages.

My footnote (the 6st) was labeled Pereira. Occuring again in a later spot, I also "pretended" to have a footnote by using the following workaround: $^{\ref{pereira}}$. It looks like a footnote, and if it is clicked it jumps to the correct one :)

• Besides that your readers will probably assume an error, this is a funny idea. +1 – Keks Dose Mar 14 '16 at 13:46

Digging this up to add a note on affiliations:

While I originally ended up on this page to do exactly what the OP intended, I agree with Keks Dose - referring to a footnote as in your example seems the more sensible option (and it's something I have frequently seen footnotes that say "See above" in books etc.)

Stephen, any decent LaTeX template should provide means of adding affiliations without having to resort to "normal" footnotes. In the LNCS template I'm using quite frequently for papers, this is achieved using the \inst command (for institute):

\author{First Author\inst{1} \and Second Author\inst{1} \and Another Author\inst{2}}

\institute{
Some university
\and
Some company
}


I don't know if there are any packages that do this, but I would think so ...

There is a particular use-case that I find occurring the most often to me: author and their affiliations cross-reference each other as it was mentioned above. For this particular case I use authblk package that works exactly as expected with most of the standard classes of documents:

\documentclass{article}

\usepackage{authblk}

\begin{document}

\author[1,2]{First Last}
\author[2,3]{Name Surname}
\affil[1]{Institute}
\affil[2]{University}
\affil[3]{Organization}

\end{document}


Simple solution: Define new command \footnoteref in preamble as:

\newcommand{\footnoteref}[1]{\textsuperscript{\ref{#1}}}


Then in your text:

\begin{document}

dummy text with footnote\footnote{Hello world\label{note1}}
then more dummy text with same footnote number\footnoteref{note1}

\end{document}


For me the combination of
\footnote{\label{label1}footnote text}
for the first footnote and
\footref{label1}
for the second footnote worked in
\documentclass[]{scrbook}
