Citation Dedup in 60 seconds: 15-30 percent of records are duplicates. #Shorts

PubMed says yes. Embase says yes. Cochrane CENTRAL says yes. The same paper is in your library three times. Pool the four-database search uncritically and 20 percent of your "records" are duplicates. Smart deduplication removes them with audit trail intact.

How the matching works:
- Exact match on DOI (highest confidence)
- Exact match on PMID
- Fuzzy match on title (Levenshtein distance threshold, configurable)
- Author + year + journal triangulation for near-matches
- Bramer 2016 Journal of the Medical Library Association validated algorithm

When records merge, the tool preserves the union of metadata:
- Richest abstract (longest non-empty)
- All present DOIs, PMIDs, and accession numbers
- Per-database source provenance (so you know it came from PubMed AND Embase)
- All keyword and indexing terms

Manual review queue:
- Borderline matches (similarity score between thresholds) shown side-by-side
- Reviewer accepts or rejects each merge
- Audit log preserved for PRISMA-S reporting

Workflow position: use AFTER searching all databases, BEFORE screening. A typical four-database search has 15-30 percent duplicates - removing them upfront saves your reviewers hours.

Export: deduplicated RIS or CSV with source-database column, ready for the screening module.

Why this matters: Cochrane Handbook chapter 4.5 mandates explicit reporting of dedup methodology in the PRISMA flow diagram. Most reviewers do it informally; this tool makes it rigorous.
