The design concept is based on the tengkolok , the traditional Malay headgear symbolising pride and respect in Malay culture. Architecturally, the tengkolok , which inspired the shape and design of the roof, a major architectural feature of the building symbolises Malaysia's cultural identity and intellectual achievement. The songket , a rich traditional handwoven fabric used for fashioning the tengkolok also inspired the design motif of the roof, effected in blue tiles. The concept of the 'mind' lends its touch in the architecture of the interior. Within the vaults that make up the atrium, immense areas of vertical spaces are laid out.
Skylight provides a contemporary counterpoint to the roof and a sense of infinite space.
The ambience of limitless space seeks to create an awakening of the intellectual faculties as the library user steps inside the foyer. The Library has a section specially built to cater for children, in the East Wing of the Library. In addition to the theatrette, the children's library has audio-visual facilities and a hypermedia centre for children. Librarians in the Common User Service Scheme are transferable within Government Departmental Libraries and the National Library of Malaysia. As at 31.12.1998, the total number of posts in the National Library of Malaysia is 306.
