[3] UKWAC archived selected websites by license or permission, using PANDAS software developed by the National Library of Australia.
The British Library worked with a broad policy of collecting sites of cultural, historical and political importance to the UK.
The whole web archive is available to registered readers on library premises; and where permission has been given, or license conditions can be met, copies are also accessible through the website.
[6] The archive gathers sites in response to events, building collections - these have preserved writing and imagery recording natural disasters, election campaigns since 2005 and the UK's blogosphere for research, among more than a hundred more.
[15] The notebooks mix description and editable code to help researchers find evidence in web archives.
