Context and content

More and more EU information is only made available on the web. However, web content has a short lifespan and web technologies evolve quickly, which means that this information is at risk of getting lost, e.g. when websites are taken offline.

To remedy this situation, the Historical Archives of the EU and the Publications Office started to create a web archive, known as EUWA, in 2013. The archive mainly contains the websites of EU institutions and agencies, most of which are hosted on the europa.eu domain.

The archive reflects the websites’ content and design as they were at a given time in the past. Thanks to this, information provided by EU institutions on their websites will always be available, even if the original site or page has disappeared.


How does it work?

Websites are archived four times a year by using the web crawler Heritrix. The crawler visits and explores the selected websites by following hyperlinks — much like a human user would — and copies the pages and files it comes across.

Users can navigate the archived sites like a live website. However, archiving with a crawler has some technical limitations and as a result certain features may not work, including the following:

  • the original website’s built-in search;
  • content that can only be reached after logging in;
  • certain navigational elements, e.g. drop-down menus, tick boxes and some maps;
  • flash animations and games, streaming media and embedded social media;
  • complex JavaScript;
  • POST functionality.

Users are redirected to the live website when archived sites contain links to an external website.
