ICSD "About" page figures (total entries, theoretical structures, metal-organic structures, new entries) extracted from Wayback Machine snapshots of icsd.products.fiz-karlsruhe.de/en/about/about-icsd, releases 2020.1-2026.1, with per-release deltas decomposed into metal-organic additions, theoretical additions, and experimental-inorganic residual. Finding: 52% of ICSD growth 2020.1-2026.1 is category expansion (metal-organic + theoretical), not new experimental inorganic structures.
