Why this record matters
The phrase “include all works for solo piano by Franz Schubert, except separate dances” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 3, 2026. The linked authority identifier is Q18163659. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1978, 1815, 1816 and 1817.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. 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.
