I have several manuscripts each with their own bibliography (*.bib file). I'm now trying to combine these manuscripts into one document having one single bib file. My problem is that I have duplicate entries in these bib files that I would like to remove.
My OS is OS X Yosemite, so I have access to BibDesk if that's an option (I mention this because this came up in several Google searches prior to me asking this question). I've also tried to use
bibtool to comment out duplicates. It works well, but only on entires that are exact duplicates. My problem is that for the same reference, I have different cite keys across my different bib files.
My question is: is there any way to clean up the merged bib file and either assign two cite keys to one reference---or---automatically detect duplicates (with different cite keys)?
