Why this record matters
The phrase “former reservoir in Effingham County, Illinois, United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Aug 5, 2026. The linked authority identifier is Q17182943. Authority coordinates are 39.109, -88.576. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1957.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
