Define the version question
Choose a public page for your own project or an organization you are researching. Write the precise question, such as whether a feature description differs from the current documentation. Keep that separate from proving that the implementation ever worked as described.
Save the current URL and the passage you can actually read. If the live page is unavailable, record that first; a snapshot is a historical source, not a replacement for current verification.
Open a capture for the exact address
Internet Archive documents entering a domain or URL and using Browse History. It also permits copying an archived page’s URL as a reference. Its calendar colours represent crawler response categories: blue for successful responses, green for redirects, orange for client errors and red for server errors. Source
Open a candidate capture and check what loaded. A calendar marker alone does not tell you that the specific sentence, image or linked document is available. If it redirects, record the destination you reached rather than calling it the original page.
Track the page and capture separately
Internet Archive explains that an incomplete capture can lead to a nearby archived date or to a live resource. Missing graphics can reflect an image that was never archived. It advises checking the timestamp embedded in the archived URL after navigation. Source
Use this comparison note:
| Field | Earlier view | Current view |
|---|---|---|
| Address inspected | Exact archived URL | Actual current destination |
| Time evidence | Capture timestamp | Your access time and any stated update date |
| Relevant wording | Passage visible in the capture | Passage visible now |
| Missing context | Unavailable image or linked page | Current access limitation |
Keep a capture timestamp separate from a date printed in the page. The former records an archival observation; it does not by itself establish when the statement was first published.
Describe the difference without adding a cause
An illustrative project page might change from “planned” to “available.” Report the two statements with their versions. Do not infer a launch date solely from the interval between two captures or claim you tested the feature.
If the passage is missing from an incomplete snapshot, keep that as a gap. Do not reconstruct it from a later page and label the reconstruction historical. Avoid using archives to assemble private-person dossiers.
For documents located through an AI answer, continue with the source-review checklist. An archive provides another dated observation; repeated copies of the same announcement remain one underlying assertion.
