History
PNAS was established by the National Academy of Sciences (NAS) in 1914, with its first issue published in 1915. The NAS itself was founded in 1863 as a private institution, but chartered by the United States Congress, with the goal to "investigate, examine, experiment and report upon any subject of science or art".
Begin with the source’s own compact description: “Proceedings of the National Academy of Sciences of the United States of America” is academic journal of the National Academy of Sciences. The dossier treats that line as a proposition to test through Proceedings, National and Academy, not as a finished interpretation.
Why this record matters
The phrase “academic journal of the National Academy of Sciences” 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 Jul 31, 2026. The linked authority identifier is Q1146531. 4 of 4 selected statements include explicit references; 3 carry qualifiers and 0 use preferred rank. The first chronological checks are 1915, 2024, 2008 and 2018.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
