I have many citations in biliography file that I am not using them in the text.

To be more specific, I have a file with name bibliography.bib and contains

@article{first, title={...}, etc}
@book{second, title={.....}, etc}

and so on. However, I am not using all of them in my document. Is there any way to identifying the references that I am not using and remove them? I am using overleaf if that's helpful!

Thank you so much for your help!

  • WinEdt has a nice macro to generate a minimal bib file from the bbl file

  • Why exactly are you worried about unused references? They will not show up your file, after all. That said, I am not aware of a fully automatic method to remove such entries.

  • Last tab of a reference in Jabref show if it is cited in one or more latex files in the directory. If no cites are found, you can delete the reference. However, I would do first a backup of the whole .bib file, just in case that you remove some reference actually cited.
