Annual capture correction table: COD intake vs estimated ICSD additions (inorganic) and CSD publication-year structures (organic), 1990-2025. Capture rate = COD intake / database production * 100. ICSD annual additions interpolated from milestones (100k in 2007, 200k in 2018, ~300k in 2024). CSD numbers from CCDC Publication Year Statistics 2026. 2025 is partial.
How to read a crystallographic-database claim: a field guide
A field guide to sanity-checking crystallographic-database claims: intake curves, capture rates, invisible provenance, and why smooth growth is backfill.
The capture correction: how much crystallography actually reaches the open database?
Over the past week I've been dissecting the Crystallography Open Database's decline from several angles: which publishers stopped feeding it, how the organic side collapsed, what space groups the rema
