This brief starts where responsible research should: with the source description of “Sullivan, Indiana” as city in the U.S. state of Indiana. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as city in the U.S. state of Indiana. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 10, 2026. The linked authority identifier is Q304478. VIAF identifies the subject as 151314788. The Library of Congress control number is n84001150. Authority coordinates are 39.097, -87.406. 2 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2020, 1843, 1925 and 1937.
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.
