List of items that appear in more than one collection

kliddle · September 12, 2018

I have one library set up to do a literature review, with collections underneath it for the relevant themes that emerge. I had an RA sorting the citations into collections with instructions to only put each citation into one collection. But, it turned out they often put articles into multiple collections. I know how to click to see which collections a given item is in. But is there an easy way to get a list of all items in the library that are assigned to multiple collections? Thanks!

I'm afraid not, no.

While not by any means ideal, there is a way do do this with the Better BibTeX plugin and a little manual work. If you install it, enable jabref4 format, and export using the now-available "Better BibTeX" format, you can look for "groups" fields in the output with a comma in it.

Whether this is workable for you depends mainly on how desperate you are. It ain't pretty.

For future reference, opening the resulting .bib file in VSCode (or any code editor) and searching for the following regular expression did the trick for me

groups = \{([a-zA-Z\s]*),(.*)\}
