Why this record matters
A short description can identify a subject without explaining its stakes. For “Byrtevatn”, the useful work is to connect “lake in Tokke, Telemark, Norway” to the records capable of establishing context and consequence.
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 23, 2026. The linked authority identifier is Q841972. Authority coordinates are 59.498, 7.836. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
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.
