Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “House Island (Maine)”, the useful work is to connect “island in Cumberland County, Maine, United States” to the records capable of establishing context and consequence.

Evidence profile

Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q5913679. VIAF identifies the subject as 315529748. Authority coordinates are 43.653, -70.208. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2022 and 1808.

Critical limits

A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. 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.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
