- The navigation menu layout is awry and the links aren’t clickable.
- Just because Wayback can’t properly rewrite the link doesn’t mean the crawler didn’t capture it. Navigate to the live site.
- Find the desired URL.
- Append the desired URL to the Wayback URL.
- In the Library of Congress Web Archives, it’s only possible to search the bibliographic records.
- The British Library and Internet Archive are exploring Lucene/Solr for full-text searching of web archives.
- Note the live site URL.
- Appending the live site URL to the Wayback URL takes you to a “snapshot” of that page in the archive.
- Full date range is wildcarded (any date), so all snapshots for that URL are presented.
- Date range is wildcarded to include only those captures from the specified year.
- An individual page in the archive.
- The time and specific resource are wildcarded, so it shows all resources captured for the specified domain on the specified day.
- An example of one of the captured resources in the list.
- Example of a live site.

- Sure enough, they’re there, and not password-protected.
