How we cite
Sources
Every record on AllTimes is sourced. We tier by how close the source is to the issuer of the number — primary sources win conflicts.
Tier 1 — primary source. The number as the issuer published it.
Bloomberg Billionaires Index. Daily-updated net worth.
IMDb-owned. Industry standard for theatrical box office; treat as Tier 1 truth source.
Annual World's Billionaires list. Source-of-wealth, country, net worth as of publication.
Official World Golf Ranking. Weeks at #1, ranking history, points.
Tour-issued earnings, tournament fields, FedEx Cup, Player of the Year.
Tier 2 — verified by a primary source we treat as canonical (e.g. a wire service citing the issuer).
Tier 3 — aggregator. Reliable but downstream of the issuer; we lean on these for fields the primary doesn't carry.
Sports Reference's soccer arm. Per-match and per-season stats with citations.
Cast, crew, release dates, runtime. Use for entity metadata, not box-office numbers.
Strong for budgets, profit, and home-video splits Box Office Mojo doesn't track.
Definitive crowd-sourced source for transfer fees and squad histories.
Tier 4 — community-edited. Used as a backbone for slugs and IDs; numbers always validated against a higher tier.
Cross-cutting structured data via SPARQL. Use as a backbone for entity slugs and IDs; verify numbers against tier-1 sources before publishing.
