This brief starts where responsible research should: with the source description of “Riehen” as municipality in the canton of Basel-Stadt in Switzerland. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as municipality in the canton of Basel-Stadt in Switzerland. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 18, 2026. The linked authority identifier is Q5262. VIAF identifies the subject as 159481817. The Library of Congress control number is n83038617. Authority coordinates are 47.581, 7.649. 2 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1958, 1157 and 2009.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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.
