Sources & method.

We rank sources by strength. T1 is the brand's own website — the primary source for what a brand says about itself. T2 is independent editorial material and Wikipedia. T3 is trade notes and retailers. T4 is weak or single-point claims. Every source in an article is labelled with its tier.

Every field in our fact base carries a verbatim quote and a source URL. If a source doesn't say it, we don't write it. Fields with only weak support are omitted rather than guessed — we'd rather stay silent than be wrong.

We state honestly whether a brand is active, dormant, defunct or acquired. The history of discontinued brands is encyclopedic value, not something we hide.

When sources disagree — about a founding year, for instance — we present both values rather than quietly picking one. That difference is what we want to show, not conceal.

Found an error? Suggest a correction, and the editors verify it against sources and update the article. An open correction process is part of the credibility, not an exception to it.

Primary source verified means the article rests on at least one primary source (T1) — the brand's own website. Secondary sources means the article cites no such source and relies on independent and trade sources (T2–T3). The label describes what the sourcing consists of, not that every claim has been reviewed by a person. Claims with only weak support (T4) are omitted, and the article then carries a note saying so. Sources are selected by the editors; the write-up is produced with the help of AI and checked against those sources.

Articles are updated as new facts arrive — acquisitions, name changes, closures. The source date is shown so you know how fresh a claim is.
