Editorial analysis

Why this record matters

The phrase “1997 book by Alexander Shulgin and Ann Shulgin” 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.

Evidence profile

Reception evidence should be dated and situated: later canonical status may differ sharply from the work’s initial circulation. The source revision retrieved here is dated Sep 23, 2026. The first chronological checks are 1997 and 1991.

Critical limits

Later fame can flatten the distinction between original context, subsequent adaptation and institutional collecting history. 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.

How to read it

Separate the work, its editions or performances, and its later reception. Catalogue records, publication histories and object files often preserve different parts of that story.
