The National Archives is the official archive of the UK government for England and Wales and the sector leader for archives in England. We are the government's knowledge and information champions, pioneers in the field of managing information. Our role is to make sure that key government information is sustainable - that it remains accessible and useable for as long as it is needed. We are well known for our unique collection of over 11 million historical government and public records - one of the largest in the world. From Domesday Book to modern government papers and digital files, our collection includes paper and parchment, electronic records and websites, photographs, posters, maps, drawings and paintings. Our repositories are filled with priceless treasures: our nation's story can be read through the documents and artefacts we hold.
