The linked authority identifier is Q1389603. VIAF identifies the subject as 11706036. The Library of Congress control number is n2004115599. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1852, 1906, 1881 and 1882.

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.
