Import the batch into a reference manager, run its duplicate detection, merge true duplicates while keeping version notes, then check each merged record's DOI for supersession before exporting a clean library.
- Import the full BibTeX batch into a reference manager such as Zotero. Zotero identifies potential duplicate items and offers a merge interface that preserves collections and tags while combining item records. Result: a list of candidate duplicate groups to review.
- Review each candidate group and merge only records that describe the same work. Keep a version note on the merged record when entries differ in venue, year, or entry type, so the merge decision stays traceable. Result: one record per work, with the differences documented.
- Check the DOI on each merged record against the metadata deposited for that DOI, for example through a Crossref DOI lookup, which returns the metadata deposited for that DOI. Result: you can see whether the deposited record points to a different version or a newer work.
- Flag records whose DOI resolves to a different title, year, or venue than the BibTeX entry, and treat those as unresolved until you confirm which version you intend to cite. Result: superseded or mismatched entries are separated from confirmed ones.
- Export the deduplicated library and keep the flagged records in a separate list for manual verification. Result: a clean source list plus a short follow-up queue.
WisPaper TrueCite checks BibTeX against real academic databases to flag references that need verification, which can support the verification step after merging.
