iCite Database Snapshot 2026-04: Bibliometrics and Citation Data for PubMed Publications

A 31.8 GB snapshot of the iCite web service provides bibliometric metrics and metadata for publications indexed in PubMed. The data includes field-adjusted influence metrics, translation scores, and public-domain citation links from the NIH Open Citation Collection. The snapshot was created by iCite and last updated on 2026-05-08.

Use Cases

• Benchmarking scientific influence based on the Relative Citation Ratio (RCR) metric.
• Tracking the clinical orientation of research papers using the Translation module scores.
• Analyzing citation networks based on link-level data from the NIH Open Citation Collection.
• Identifying primary research articles using the 'is_research_article' flag.

Strengths

• Large-scale data at 31.8 GB, likely covering a substantial portion of PubMed.
• Provides specialized, field-adjusted metrics like the Relative Citation Ratio (RCR).
• Includes multiple data modules (Influence, Translation, Open Cites) in one snapshot.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent for many fields; field semantics must be inferred after download.
• Data freshness should be verified as the snapshot is from April 2026.
