# [LaTeX tip no. 2] Multiple use of footnotes

Imagine you put your citation-commands in a footnote – something like

`...foo\footnote{\cite{Smith2000}, p. 42}`

Now imagine you have another citation which uses the same citation mark:

`... bar\footnote{\cite{Smith2000}, p. 42}`

So you have two identical citation marks in footnotes on one page … not very nice huh? So why do you not use the same footnote for both citations? It’s very easy done with a macro:

`\newcommand{\lastfootnote}{\footnotemark[\value{footnote}]}`

It tells the Latex system to use the last footnote identified by the counter – value{counter} returns the value of the last footnote counter (you guessed so, huh?)

Now you can use it like this:

`... foo\footnote{\cite{Smith2000}, p. 42}`
`.....`
`... bar\lastfootnote`

Both words, foo and bar, will have the same footnote counter referring to one single footnote. Pretty neat!

Did I mention that I start to love Latex? 😉
