The National Library of Australia is one of several agencies within the Department of Infrastructure, Transport, Regional Development, Communications and the Arts portfolio.The Library's role, as defined by the National Library Act 1960, is to ensure that documentary resources of national significance relating to Australia and the Australian people, as well as significant non-Australian library materials, are collected, preserved and made accessible either through the Library itself or through collaborative arrangements with other libraries and information providers.By offering a strong national focus in all that we do, and cooperating with others who share our goals, we support learning, creative and intellectual endeavour, and contribute to the continuing vitality of Australia's diverse culture and heritage.
