The 2026 Journal Citation Reports (JCR, 2025 Edition), a database that evaluates journal impact based on Web of Science data, was released on June 17, 2026.

This year’s release, titled the ‘JCR 2025 Edition,’ provides various evaluation metrics—including the Journal Impact Factor (JIF)—based on Web of Science citation data from 2025.
