Consider this illustrative situation: A centenary date will arrive whether the archive is ready or not. A strong celebration first establishes which stories are true, who may speak and what should still be useful after the event.
An anniversary, award, championship, opening or leadership moment will create unusual attention. The visible request may be a book, move, announcement, licence, archive, event or venture. The real question is what becomes harder to reverse once the first commitment is made.
A rushed response can expose archive gaps, contradictory stories and generic outputs that cannot be repaired after the moment passes.
