I would like to merge two bibtex files which have a lot of overlaps and duplicated entries. Since these two bibtex database files are for different chapters of my dissertation, what is the best way of merging these database files? I have all chapter content finished, just need to make sure the References cited in the whole dissertation doesn’t duplicate in the end.
In my mind, I have the following workarounds/approaches:
Merge two files while always stick to the bibtex key of file A using JabRef. After merging, give me a log file on where bibtex keys were changed so that I can update my chapter citations accordingly. For this approach, I am sure if I can easily find this log file to track the changes in JabRef.
Use the two files separately for the two chapters or cite both bibtex files for all my dissertation content, so that I don’t need to change anything in the citations in my writing. At the end of the References section of my dissertation, all duplicated entries should be merged automatically–that is no duplicated info in the References section. Is this possible in general? I know this approach might not be related to JabRef functions, but I appreciate if anyone knows bibtex better than me to give a clue.
