Did you know from May 2014 The National Archives began to archive tweets and You Tube videos published by UK central government departments from their official Twitter and YouTube social media platforms. There is already a substantial archive of material dating from 2006 captured during a two year pilot project.
Videos can be filtered by year of creation and there is a search facility, as for example, videos from HM Treasury
Tweets are arranged in a date span but cannot be searched, as for example, tweets from the Home Office
Where tweets contain web links these should be operational as long as they are within the UK Government Web Archive. Retweets are not archived as are tweets for non-government organisations that form a conversation. Web links within tweets that are not part of the UK Government Web Archive will receive a 404 or 410 error message that will allow users to see the destination of a link. This may then enable users to search for that link elsewhere.
For more information see the ‘Using the social media archive‘ section on the National Archives ‘Information on web archiving‘ page.
