Keep a Search Log That Includes the Searches That Found Nothing
An unsuccessful search is useful information when you know what was searched. “Nothing online” tells a future researcher very little. “Searched this collection for these name variants across these years” gives the next attempt a starting point. Keep the log small enough that you will fill it in while working.
Choose one research question for the session. Write it at the top of the page or record. A question about a business’s location in one decade should not quietly become a search for every person who ever used its name. Interesting side paths can go on a separate list.
Record the scope before the result
| Field | Useful detail |
|---|---|
| Source | Collection or volume, repository and link or identifier |
| Coverage checked | The dates, pages, sections or filters actually used |
| Search | The exact words, spelling variants or browsing route |
| Result | A relevant item, an uncertain lead or no result in that search |
| Next action | A specific follow-up that the result suggests |
Use your own wording rather than forcing every project into a complex database. The important distinction is between what a collection claims to contain and the portion you actually inspected. If you only searched an index, do not record that you read the complete records.
Note the search settings that affect the result. A date filter, a phrase search or a restricted section can exclude material you later want to consider. If you changed the settings, record the meaningful attempts rather than every accidental keystroke.
Describe “not found” narrowly
A failed name search can have several explanations: a variant spelling, an incomplete index, a collection outside the relevant period or a genuinely absent record. The log does not need to choose among them immediately. State the result and identify what you have not yet tested.
When you browse page images, note the range and any pages you could not inspect. A missing or unreadable page is part of the search boundary. Do not treat it as empty evidence simply because you could not extract information from it.
Save uncertain leads with a reason for uncertainty. A matching surname in another county may be worth checking, but it should not enter the established timeline as a fact. Give it a separate status so it remains findable without gaining undeserved confidence.
Leave the next session an entrance
End with one concrete action. “Check the adjacent year’s directory for the business name” is easier to resume than “research more.” Include the relevant link or catalog reference so you do not spend the opening minutes rediscovering the same source.
Review the log before repeating a search. Conditions may have changed, or you may have a new spelling that justifies another attempt. Record that reason. Repetition can be productive when it tests something new, rather than happening because the earlier work disappeared from memory.
Keep the log with the source files and provisional account. It documents the route behind the story, including its limits. Another person should be able to tell which question you pursued and where the evidence stopped, without mistaking a quiet search result for a final answer.
