Restrictions to Crown Copyright material mean, however, that, when it comes to social media archiving, the UKGWA can capture only the UK Government's side of the conversation with the public.
Between 2004 and 2008 the UKGWA mainly held copies of websites created by departments of state and those of UK Public Inquiries.
During 2007, Members of Parliament became aware of the increasing problem of link rot on UK government web sites.
Web Continuity required UK Government website managers to work with the UKGWA to capture copies of any material about to be removed.
From 2014 the UKGWA has captured part of this material: official tweets on Twitter and government videos released on YouTube.
