Review Duplicate Zotero Photo References Without Deleting Source Evidence
By ImgHeal · Updated
Zotero duplicate suggestions concern reference records, not a forensic comparison of photo bytes. Review the source identity, notes, and attachments before merging candidates. Two records showing the same portrait may describe different prints, reproductions, or catalogue sources that should remain distinct.

Establish the object and source represented
Open both candidate records and compare stable archive IDs, repository links, creators, date notes, and attachment roles. Check whether one describes a print and the other a later publication reproducing it. Inspect front and back scans where available. Similar titles such as Family Portrait are weak evidence of duplication. Preserve any conflicting descriptions and research notes before modifying records so the reason for a later decision remains visible.
Understand what the suggestion actually checks
Zotero documents bibliographic fields used in duplicate detection and provides a supported merge review. Treat the suggestion as a lead to inspect, not as authority to discard a source. Compare the actual image files separately if byte equality matters, using a checksum workflow appropriate to the archive. An edited JPEG and untouched TIFF are expected to differ even when they show the same photograph. Keep object-level provenance distinct from file-level duplication while deciding whether the reference records genuinely represent one resource.
Verify the retained record's completeness
If a merge is appropriate, follow the current documented process and inspect the resulting fields, notes, collection memberships, and attachments. Confirm that a back inscription or alternate source citation did not become difficult to locate. Test an existing citation workflow where relevant before assuming a tidy library view proves all references are intact. Keep the archive masters independently protected. Do not remove a source scan merely because a restored viewing attachment looks clearer or a bibliographic duplicate tool presents the records together.
Check this workflow
- Compare archive IDs and source roles.
- Separate record duplication from file equality.
- Inspect notes and attachments after an accepted merge.

Questions about this restoration task
Does Zotero's duplicate view prove the attached images are identical?
No. Review the reference records and compare image files separately for the question you need to answer.
