Catalogue description National Physical Laboratory: Departmental Websites, and Websites of Associated Agencies and Bodies

This division contains National Physical Laboratory websites, together websites of agencies and other bodies associated with the National Physical Laboratory .

These are websites archived regularly as part of The National Archives' website collection policy. For information about the appraisal decisions informing the scheduling and selection of these websites, please refer to Operational Selection Policy OSP 27: The selection of government websites.

The selected websites have been gathered (or crawled) from the Internet in a variety of ways, by various organisations including the Internet Archive, the European Archive and the UK Web Archiving Consortium. They form part of the UK Government Web Archive, along with one-off gathers which are collected in response to topical issues or unusual circumstances (such as capturing the website of a body not regularly collected prior to it winding up), or as part of a themed collection. The frequency at which each website is gathered is scheduled; the frequencies vary (from weekly, to monthly, six-monthly or annually) and can be subject to change, especially where the functions of the body represented by the website alter.

Some websites which were transferred directly to The National Archives from government departments rather than being gathered from the Internet can be found in the UK Government Web Archive. For further information on the gathering process, please see the UK Government Web Archive.
