# Determining which references have not been cited [duplicate]

Unused bibliography entries - how to check which entries where not used?

I have a very large `references.bib`. Throughout my document, I have used `\cite{}` to cite many of them. Now I would like to know if I missed any - that is, if there is a references in the `.bib` file that has not been called using `\cite{}`. Is this possible?

You can use `backref`, part of the `hyperref` package. It will add links in the bibliography to the pages where the entries are cited. That way you can easily find references you did not use.
``````\usepackage[backref]{hyperref}
