Yearly quartile comparison

Scimago (SJR) for all years; Clarivate (JCR / JIF / JCI) from 1997 onward. Latest year stays open; older years start collapsed.

WoS / JCR data covers 1997 onward.

Note: JCR Q, JIF, 5Y JIF, JCI, and JCI Q are blank before 1997 — WoS/JCR data on this site starts in 1997.
