What we hold, exactly
10 countries × 9 series = 73 series held. Coverage is deliberately uneven — a market with more statutory instruments carries more series — and this table shows the shape rather than leaving you to find it. ✓ links to the series page with its citation; – means we do not hold it (and the API 404s rather than improvising).
