# Cross-reference statistics v2

As of **2026-11-10**; 2,023,221 dated case records (of 2,023,221); unknown dates: 0.

Counts are one edge per stored case record and section after subsection roll-up. Publisher duplicates remain possible. The velocity comparison uses complete periods 2016–2020 and 2021–2025, normalized per 1,000 case records; it is descriptive citation activity, not a causal trend estimate.

Velocity denominators are 73,807 and 244 case records respectively. Sparse late-period coverage makes velocity rankings unstable and unsuitable as a corpus-wide trend estimate.
