Why this ranking is different

The composite SourceScore Index averages all three sub-scores — Citation Discipline, Modern Reference, and Citation Velocity. This page surfaces the SAME source pool but ranks ONLY by Modern Citation Reference. The biggest re-shuffle: DOI (CrossRef Resolver) jumps 9 positions vs the composite Index ranking.

Use this view when modern citation reference is the signal that matters for your citation decision. The composite Index is the safer default; this dim-faceted view is the precision lens.
