Duplicates with the same title are not being detected

I'm in the process of merging my Calibre library and my Zotero library. Everything is going great, but Zotero's duplicate detection is overlooking about 300 books that my human brain perceives as obvious duplicates.

They have the *exact* same title. That alone should flag them, in my mind.

I saw a thread where some people were requesting a more thorough method for detecting duplicates, with things like PDF text comparison. My problem seems to be the opposite: I want to figure out how to make it "dumber." I'd like to know how to make it flag any cases where books have the same title.

Any ideas?
  • If it matched only on title there'd be many more false positives.

    If both books have a year and they're off by more than one, it won't be a duplicate.

    Same if they both have a DOI or ISBN and they don't match.

    Same if they don't have at least one creator that matches last name + first initial.

    If you're not sure what's causing them not to match, export both items to RIS and post the output here.

    Note that, if all you care about is the title, you can just sort your library by title, select two or more items, right-click, and choose Merge Items.
