The UK Central Government Web Archive is a selective collection of UK Government websites, archived from August 2003, which has been developed by the National Archives of the United Kingdom, using the services of the Internet Archive. […]
A recent study suggested that there are currently approximately 2,500 separate UK Government websites. This project is being undertaken as part of the ongoing development of a web archiving strategy by the National Archives. 51 websites have been carefully chosen as a representative sample of the entire UK Government web domain, and have been selected in accordance with criteria designed to reflect the overall functions of government. A number of departments and agencies were then chosen which are representative of each of these functions. This provides a broad cross-section across UK Central Government.
The websites are harvested at varying intervals, to provide the flexibility to respond to changing circumstances. Initially, 10 websites are harvested every week, and the remaining 41 are harvested every six months.
The Internet Archive will also be supplying copies of the websites collected to the National Archives, for long-term preservation by our Digital Preservation Department.
