The UK Web Archive is based at the British Library. They collect, make accessible and preserve web resources of scholarly and cultural importance from the UK domain. As of February 2012 nearly 10,000 websites have been archived there.

Contributors to the UK Web Archive seek permission from the website owner for every website it archives though this is costly and difficult. Users can see how a website evolves over time by accessing the snapshots (“instances”) that the archive takes at regular intervals.

The archive is free to view, accessed directly from the Web itself and, since archiving began in 2004, has continued to grow at a rate of several hundred per month. These can be searched by name and category and viewed in a number of dynamic visualisations including N-grams, tag clouds and 3-D walls. Users can also nominate sites for inclusion.
