Latex in text link to bibtex or footnote, and bibtex/footnote link back to place in text

Question

In Latex, what I would like to is have a link from a paragraph to a footnote or BibTeX reference, and have a link in the footnote or BibTeX reference back to the paragraph or place in the text where the original link was clicked. Create a circular link reference if you will. References will only be used once.

This may be a bad/non-latex example of what I want, but it demonstrates what I'm trying to do.

In this article, I can click the superscript in the article to go to the footnote, AND you can click the superscript next to the footnote to go to where it's used in the article! Which is what I want to do for my references in Latex.

Answer 1

Having a look around just found about the pagebackref option in the hyperref package, which can be loaded this way:

\usepackage[pagebackref=true]{hyperref}

It uses backref, so you can modify the formatting as explained here.

This provides the back references for the references shown in the bibliography, not for footnotes. A question some years ago led to a package named footnotebackref which relies on hyperref to provide the feature you requested.

However, backref is not compatible with biblatex, thus the previous solution will work if you use natbib to manage references. You can have a look here to have the bibliography back reference done with biblatex.

I haven't checked if footnotebackref is compatible with biblatex. Since biblatex can also print bibliography references as footnotes with back references, I suppose they may crash, but I'm not sure about it.
