Working Around Gaps in Provenance
Launch library · evergreen read

Not every document arrives in an archive with a clean, fully documented path behind it. Sometimes a collection was purchased from a dealer with limited records of its own, or inherited through several hands before anyone thought to note carefully where it had actually been over the years.
A gap in provenance does not automatically disqualify a source from use, but it does raise the bar for corroboration considerably. Internal evidence, such as handwriting, paper type or references to independently dated events, can help support a document even when its custodial history remains genuinely thin.
The honest approach is to name the gap plainly in your own notes and, where relevant, within the finished piece itself. Readers trust writers who acknowledge uncertainty far more than those who quietly smooth it over for the sake of a cleaner story. This is especially true when a document's content is otherwise unremarkable, since a shaky provenance can undo even the most carefully argued analysis built around it.
