How can a file be produced that another reader can verify ?

  1. Define a question, scope, deadline and stopping rule before choosing tools.
  2. Keep a source log distinguishing original, republication, commentary and hypothesis.
  3. Test an alternative hypothesis and look for contradictions.
  4. Present established facts, unknowns, limitations and the next action with accessible references.

Keep these fields in the source log

  • Question and conclusion criterion
  • URL, author, date and working copy
  • Fact, interpretation and justified confidence level

What the method cannot establish alone

More tools do not make sources independent. A useful file prioritises relevant evidence and wording proportionate to uncertainty.

Questions about tools and external searches

Where are search results displayed?

On the selected provider’s website, in a new tab. IIS does not retrieve, host or display investigation results. Directory filters only filter the editorial catalogue.

Is the typed query stored?

The launchpad builds links inside your browser, without sending the query to IIS or storing it in browser storage. Clicking a prepared link sends the query to the named provider, under its own rules.

Are all tools free and available in every language?

No. Access may require an account, subscription, software or quota. The catalogue is available in French and English; providers set their interface languages, coverage and conditions.

Does no result prove that a fact is false?

No. Index coverage, spelling, language, access limits and capture dates can explain a missing result. Record what was searched and what remains unknown.
