Why this record matters

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 Sep 10, 2026. The linked authority identifier is Q5127673. Authority coordinates are 38.549, -75.148. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
