To browse content in the web-archive:

  • Clicking on the entry will take you to a timeline that shows captures of the selected site. Clicking on the years will expand the timeline and show the dates that the site was captured on.
  • To view a capture on a particular day, click on the blue box with the date in it.
  • You can then browser the website as you would a live site. Some aspects of the site may not work, for example, search boxes that were on the site.

To browse content in the Twitter archive:

  • Clicking on the account will bring up a list with all the captured posts from that site.
  • It is possible to refine the posts being shown by using the date range selector and sort options at the side of the feed.

Search tips

Here are a few hints and tips for using the web-archive in other ways:

  • If you know the exact URL that you want to look at but not what to search for on that page, then you can go to the timeline for that URL without going through the search engine. For example, if you want to see all the captures for, then you can add the URL of the live site to*/, then this will bring up a complete overview of all the captures of that site.
  • The web-archive shows all the dates that a site has been captured, but these may sometimes be only partial captures of a site. This is due to the crawler sometimes capturing bits and pieces of other websites as it is archiving a targeted URL. This is because of the nature of how websites are interlinked, and as the crawler finds embedded content.
  • A "Document not found" message may appear when navigating the archive, indicating resources that UNFCCC has not archived. This is the case for content hosted on sites that are not operated by UNFCCC.
  • The date of capture may change as you navigate the archive, since the archives are interconnected and interlinked. If a resource has not been archived on a particular date, the web-archive software points you to the closest resource for the content that is missing.
