Mature Journal Rankings
Journals with at least 60 months of publishing history — evaluated through AJR-M, the mature-journal track of AJR (POSI Automated Rating) (citation-weighted: Citation Performance, Output & Stability, Governance & Integrity, Infrastructure, Reach, Transparency), ranked as M-Q1–M-Q4. M-Q ranks independently of Citation Q — see AJR-M-1.0-SPEC.md.

A mature journal is never scored with the AJR-E rubric (the early-stage 100-point evidence model) — any interim AJR-E-based figure computed for a mature journal earlier in POSI's history is retained only in historical data, never shown here as a current mature score. The 2695 Global Benchmark rows below (no evidence crawl run at this scale) show a diagnostic OpenAlex citation preview only — not a score, not ranked; see the Citation Preview column and Citation Rankings.Lifecycle window: 60+ months since first publication

Global Benchmark rows (Collection: Benchmark, no AJR Score) are the 2026-08 Elsevier/Frontiers publisher-catalog expansion — bulk-ingested, not individually vetted, never an admission candidate, loaded client-side from a separate data file (not part of this page's initial HTML). Their Citation Preview is diagnostic only (OpenAlex 2yr mean citedness, not PCI, not ranked) — see Global Benchmark Collection.
