Why this record matters
“Moriyama, Shiga” is worth following because a concise public description often conceals a longer documentary argument. Here, Moriyama, Shiga and city provides the most credible route into that argument.
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 17, 2026. The linked authority identifier is Q857225. VIAF identifies the subject as 258732192. Authority coordinates are 35.059, 135.994. 4 of 5 selected statements include explicit references; 1 carry qualifiers and 1 use preferred rank. The first chronological checks are 2021, 1533 and 1603.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. 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.
