About
The National Archives is the United Kingdom's official national repository of government records, holding one of the largest archival collections in the world spanning more than 1,000 years of history. Based in Kew, Richmond, it serves as the definitive source for primary historical documents including Cabinet Office files, legal records, census data, military records, and much more. Researchers, genealogists, historians, educators, and the general public can search the online catalogue to discover millions of records, many of which are available digitally. The archive regularly releases previously classified government files under the 20-year rule, making it an essential resource for contemporary history. Beyond records access, The National Archives offers in-person reading rooms for on-site research, award-winning educational resources for students and teachers, professional guidance for information managers and archivists, and a podcast series — 'On the Record' — that brings historical stories to life. It also maintains related services including the UK Government Web Archive, Legislation.gov.uk, and Find Case Law. As an Independent Research Organisation, it supports academic collaboration and provides best-practice guidance for the wider archives sector. All content is made available under the Open Government Licence, making it one of the most open and accessible public knowledge repositories in the world.
