The Verifera Encyclopaedia is Verifera's standard for evidence-graded, verified reference knowledge. It is not a single website section — it is a methodology and a mark, published as subject editions wherever Verifera-verified knowledge lives. Every entry shows its sources and the date each fact was last verified; the "Verified by Verifera" mark appears only when every fact on a page is within its review window.
The editions
- Verifera Encyclopaedia · Health — evidence-graded knowledge about health products and claims (published at camdenmedicals.co.uk).
- Verifera Encyclopaedia · Healthcare Careers & Credentials — verified knowledge about professional registers, credentials and pathways (published here).
The editions are peers — neither owns the name. The bare "Verifera Encyclopaedia" refers to the standard only; every edition carries its subject label.
What "Verified by Verifera" means
- Every fact is a sourced claim — a primary-source citation plus the date it was last verified.
- Freshness is enforced, not assumed — volatile facts are re-checked quarterly, stable facts yearly; a page with a stale fact cannot publish.
- Honest uncertainty over false confidence — where evidence is weak or a rule is in transition, the page says so, and the mark is withheld.
- The mark is bypass-proof — it renders from the verification state, never hand-set.
