Editorial summary

“List of highways numbered 45” enters the record as wikimedia list article. Crown Archives preserves that source wording while asking what List, highways and numbered can confirm, complicate or overturn.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 361-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its strongest next move is a source search built around List, highways and numbered.
Editorial analysis

Why this record matters

“List of highways numbered 45” is worth following because a concise public description often conceals a longer documentary argument. Here, List, highways and numbered provides the most credible route into that argument.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 9, 2026. The linked authority identifier is Q58426340. None of the 0 selected statements returned an explicit reference.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
