This question already has an answer here:

I have a document in which I have a footnote ("footnote 1") with some special explanation. Later in the document there is a need/want to appeal to this special explanation. In this second instance, I thought about having a footnote ("footnote 2") which goes to the bottom of the page as usual, and in which I just write "See footnote 1".

However, I think it would be better if I could simply refer to footnote 1 in the text, instead of using the middle-man footnote 2. Is this possible?

My failed attempt:

London is in England\footnote{London is the capital city of England. \label{footnote 1}}.\\
London is a city\ref{footnote 1}.

A picture speaks a thousand words: enter image description here

Is this bad practice?

What is the problem exactly? The referencing seems to work fine, but you should write London is a city, cf. footnote \ref{footnote 1}, then it won't look quite as awkward. –  Anke Apr 15 '13 at 14:58
@Anke The problem is that the number ("1") is not in the superscript position. –  User 17670 Apr 15 '13 at 15:04
Why would you want to have it as a superscript? That would look really weird IMHO... A footnote is a superscript, but the reference is just the number. If, however, you don't want to refer to the footnote, but reuse it, you could just use $^{\ref{footnote 1}}$, which looks like really bad tex code, but works... –  Anke Apr 15 '13 at 15:06
An aside: I think footnote should be put after the punctuation. See Do footnoting superscripts go inside or outside punctuation? –  Kevin C Apr 15 '13 at 15:10
@Anke Yeah, that's what I was looking for. Thanks. But, do you think this is bad typographical practice? –  User 17670 Apr 15 '13 at 15:13

If you are using KOMA-Script or memoir there is a special macro \footref.

If you are using usual article class use \textsuperscript.

The following MWE shows the possibilitys (I added a comment from @Anke to the question):

\documentclass[11pt]{article} % scrartcl article memoir 
London is in England\footnote{London is the capital city of England. \label{footnote 1}}.

London is a city\textsuperscript{\ref{footnote 1}}.

London is a city$^{\ref{footnote 1}}$.

%London is a city\footref{footnote 1}.  % Only for KOMA-Script or memoir

footref worked for me. Note sure what this KOMA thing is though. –  User 17670 Apr 15 '13 at 15:20
@User17670 Funy. On my system (MikTeX 2.9) my MWE throws an error message with class article and deleted comment sign ... I added a link to KOMA-Script in my answer. –  Kurt Apr 15 '13 at 15:24
@User17670 if \footref works for you in an other than a KOMA-Script class you might be using a package that happens to load the package scrextend. The memoir class also provides \footref. See also tex.stackexchange.com/a/74668/5049 –  cgnieder Apr 15 '13 at 18:02
@cgnieder I added memoir to my answer. –  Kurt Apr 15 '13 at 20:39
