This brief starts where responsible research should: with the source description of “Allan A. Swenson” as american author, literary agent and master gardener. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as american author, literary agent and master gardener. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q20738203. VIAF identifies the subject as 92688688. The Library of Congress control number is n79026908. None of the 3 selected statements returned an explicit reference. The first chronological checks are 1933 and 2023.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. 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.
