How can I decide whether a source is current enough for the claim it makes?

Judge the age against the particular claim, not the page as a whole. Ask how quickly that claim could change and what might happen if it were out of date.

A general explanation of a long-established idea may remain useful for a long time. A claim about a current price, schedule, software version, availability, or policy may need more recent checking. These are examples, not a universal expiration schedule: the right interval depends on the claim and its importance.

Then inspect the evidence behind the wording. A recent page can repeat old material, while an older page may point to evidence that is still relevant. If the page doesn’t say when its evidence was collected, record that uncertainty rather than assuming the publication date answers the question.

Not by itself. Separate three dates where possible: when the underlying information was gathered, when the page was first published, and when it was last revised. An update date shows that the page was revised, but unless it explains what changed or when the evidence was checked, it doesn’t establish that every claim was reviewed.

Look for clues tied to the specific statement: a dated document it relies on, a description of the review, or a note identifying which details were refreshed. If you can’t tell whether the relevant claim was revisited, don’t treat the update date as proof that it is current. You could write: “This page was updated on [date], but it doesn’t specify when this detail was verified.”

Break the page into individual claims and assess each one separately. Don’t label the whole source simply “current” or “outdated” if only some details are time-sensitive.

For example, suppose a guide explains a general process and also lists a registration fee. You might use the process explanation as background while checking the fee against recent evidence that directly addresses it. If you can’t verify the fee, omit it or mark it as unverified rather than letting the page’s general usefulness lend it unwarranted certainty.

A working note could look like this:

Claim: the registration fee is $25 Evidence date: unknown Page date: updated last week Could it change? Possibly Cost if wrong: depends on how the information will be used Decision: verify before repeating

The amounts and dates here are hypothetical. These labels are judgments, not guarantees. For a claim with serious consequences, use a stronger verification standard and seek evidence that addresses that exact detail.

Apply the same short test to each claim:

1. State the claim precisely. “The page is current” is too broad; “the listed fee is $25” is checkable.
2. Find the evidence date, not only the page date. If it isn’t stated, record “unknown.”
3. Consider how quickly that detail could change and what the cost of stale information would be.
4. For changing or consequential details, seek recent evidence that directly supports the claim. If you can’t find it, qualify or omit the detail.
5. Keep the source and date with your notes so you can reassess later.

For the hypothetical fee above, a recent update date doesn’t tell you when the fee was checked. Since the evidence date is unknown, verify the amount before repeating it; if you can’t, leave it out. This method helps you judge whether a source is suitable for a claim, but it cannot establish that the source is accurate or complete.
