The National Archives of Singapore is the national archives of Singapore. It was formed in August 1993 with the merging of the National Archives and the Oral History Department. The NAS is responsible for the collection and management of records relating to the nation's political, social and economic history. NAS also identifies and collects records of historical significance from local and overseas private sources. In 1993, both NAS and the National Museum of Singapore were brought under the administration of the National Heritage Board. Since 1 November 2012, the NAS was brought under the administration of the National Library Board. The National Archives was originally established in 1968 for the preservation and administration of the nation's archives. It holds records as far back as 1800, 19 years before the arrival of Sir Stamford Raffles and the founding of the modern nation. The Oral History Centre documents the history of Singapore through the use of oral history methodology. NAS has a selection of archival materials available for viewing by the public, including public records, building plans, oral history recordings, photographs, electronic records and an audio-visual collection of microfilms, films, videotapes, colour slides, negatives and maps. Nowadays, the NAS has improved access to archives by allowing researchers and history enthusiasts to access archives online. Requests for archives are made easier with a new online system replacing the need for forms. Since then, the NAS building had undergone an 18-month revamp in 2017, the first time since it moved there in 1997. The revamp would fix wear and tear, including water-seepage and paint peeling, as well as enhance the look of the building with restorations to reflect the building's past. These changes will allow the building to blend with its surroundings. The building reopened on 7 April 2019 with better facilities, with an expanded Oldham Theatre taking 132 people instead of 44 before, three new oral history recording studios, microfilm readers and expanded conservation labs, as well as lifts installed and levelled floors for the disabled.
