# latex, how to put superscript and link to URL downpage

In a document, how do we do this:

i.e. how to put a superscript and then link it to a link as shown in the diagram?

Perhaps I am misunderstanding the question? It seems that all you need is a \footnote with an \url from, for example, the url package:

\documentclass{article}
\usepackage{url}

\begin{document}

\vspace*{\fill}

text\footnote{\url{www.stackexchange.com}}

\end{document}


The \vspace*{\fill} line was just to push the text to the bottom of the page for the example; you don't need this in your document.

• when do we use footnote, why don't we just provide it as a reference? – Noor Apr 18 '13 at 18:24
• @user1774937 I'm afraid I don't understand your question. Could you please elaborate a little? – Gonzalo Medina Apr 18 '13 at 18:28
• I've seen in many research papers that they use footnote, I'm just trying to google around but did not find a good explanation. When do we use footnote? – Noor Apr 18 '13 at 18:33
• @user1774937 I am not friend of using footnotes, as Bringhurst says (p.68 of his Elements): "Footnotes are the very emblem of fussiness"; however (paraphrasing Bringhurst), short, infrequent footnotes might be acceptable. When to use a footnote? Some say that when you need to comment on or cite a reference for a designated part of the text. My recommendation is, however, if possible, never to use them. This can be very debatable and a comment is clearly not the place to discuss this in depth. – Gonzalo Medina Apr 18 '13 at 18:41
