The National Archives’ collection of records primarily traces Government’s decisions, transactions, and activities, from colonial to self-rule.

The collection also consists of other records of historical importance generated by private organizations and individuals, such as newspapers, journals and yearbooks. While the majority of records are documents and bound volumes, there are also microfilm, maps, photographs and audiovisual records that provide valuable historical information. The collection is complemented by a small Reference Library collection, as a first point of entry for research.

Collectively, the National Archives’ records help to foster a better understanding of our democracy and our heritage.

The collection is complemented by a small Reference Library, an indispensable resource aid for  researchers.
