An extensive collection of British colonial archived reports and books, curated from Sultan Nazrin Shah’s personal repository, is available for viewing by interested researchers. This collection offers an unparallel perspective on the social, economic, and administrative aspects of the Straits Settlements (SS) of Penang, Melaka, and Singapore (and Labuan, a SS between 1907–1946), the Federated Malay States (FMS) of Perak, Selangor, Negeri Sembilan, and Pahang, and the Unfederated Malaya States (UMS) of Kedah, Perlis, Kelantan, Terengganu, and Johor, as well as North Borneo (Sabah) and Sarawak, as these territories developed. Many of the publications contain valuable time series statistical data, interpretation, and commentary written by leading lights of the colonial era.
