The link works.
Does the claim?

A link at the end of a sentence can look reassuring. Open it before you let it vouch for the whole sentence.

The page may discuss the right subject without supporting the particular thing you wrote. It may describe a different group, a different period or a different measure. Finding the right topic gets you started; finding the relevant passage lets you compare.

Find out what you have actually reached.

Is this the original research, a report about it or a summary quoting another summary? Follow the reference when you can. Several pages may lead back to one underlying source, so count independent support with care.

Read around the sentence you want to use. The next paragraph may contain a condition or an exception. Keep enough context in your notes to understand the passage when you return to it.

Let a missing passage stay missing.

If you cannot find the support, record that. You may need a more suitable source, different wording or a decision to leave the claim out. Do not fill the gap with confidence simply because the link looks respectable.

Make it easier for the next reader.

Keep the source title and URL, the exact passage, the relevant date or period, and anything still unresolved. The source-notes sheet can help you keep that manual record. It runs in the page and does not send your entries to a server.

Verity helps you check factual claims and review the sources behind them before you publish. A returned link still deserves a read. Bring one sentence from your work and see whether the check helps you decide what to do next.
