Latvijas Nacionālā arhīva, Latvijas Valsts arhīvs

The Central State Archives of the October Revolution and the Socialist Construction of the Latvian Soviet Socialist Republic was established by Decision 831 of the Latvian SSR Council of Ministers (CM) of 31 December 1961. The Statute of the Central Archives of the October Revolution was accepted on 22 April 1962, according to which the Archives were to be a research institution tasked with the preservation of documentary material of the Latvian SSR (1917-1919; 1940-1941). The name was changed to the State Archives of Latvia (SAL) on 1 May 1991. The Archives were supplemented with documents from Socialist and Communist organisations, from the Latvian SSR CSS (Committee for State Security [KGB]) documents, from public and political organizations, and from Latvian exile and juridical organisations. After the archival system was reorganised, the National Archives of Latvia (NAL) was established as a direct public administration authority on 1 January 2011. The State Archives of Latvia became a structural unit of NAL. 

Staff of NAL State Archives of Latvia can copy documents (including digital copies) for researchers. The NAL Department of Preventive Preservation addresses questions concerning specific reproductions, as well as microfilming of archival documents, restoration of documents, document binding, and complex analysis of paper and carton. NAL Latvia State Archive of Audiovisual Documents addresses question concerning specific reproductions of video, audio, and other visual documents. 

As of 1 January 2014 the NAL State Archives of Latvia hold 3,164,852 archival units 33,283 linear meters long. The building at Bezdelīgu iela 1 stores 1,070,773 archival units (13,410 linear meters). The building at Skandu Street 14 stores 2,094,079 archival units (19,873 linear meters). 

On 30 December 1961 the Latvian Soviet Socialist Republic CM decided to reorganise the Archive department, and in 1962 renamed it the LSSR CM Archive management; the LSSR State Archive was renamed the Central State Archive of History. On 1 January 1961 a decision was made to establish the Central State Archive of the October revolution and Socialist Construction of the Latvian Soviet Socialist Republic; after Latvian independence, this archive was renamed the State Archive of Latvia (SAL) on 1 May 1991. Under the State Administration Law of the Republic of Latvia, this system of Archives was reorganised and the National Archives of Latvia (NAL) was established on 1 January 2011. The State Archives of Latvia subsequently became a structural unit of the NAL.
