Could an AI history search miss a newspaper story that was there all along?

An AI assistant helping with a town history might report that it found no newspaper mention of an event. I would keep that sentence out of the finished history unless the search limits are explained. The Library of Congress's April 2025 account of reprocessing Chronicling America includes a useful example: a newspaper paragraph whose old machine-readable text was mostly unrecognizable. After reprocessing, articles like it could appear in keyword search results. The historical page had not changed. The text used to find it had. That gives an old unsuccessful search a reason to be tried again. It also means that asking an assistant to search more quickly cannot, by itself, settle whether the archive contains a mention. The Library's current FAQ warns that tiny fonts, markings and microfilm quality can cause recognition errors; it also notes that not every eligible period has been selected or made available. For a local-history project, I would have the assistant record the newspaper titles, dates and terms it searched. If you have a likely issue date, open the page images rather than rely only on the text index. Keep 'no match found in these searches' separate from 'the event was not reported.' These are research steps I would use, not an AI search I have tested. A town's story should not lose a person simply because software could not read their name.
