Unfortunately, the National Library of Australia is unable to donate books to assist in developing other libraries. The Library's main role is to build, preserve, and make available a collection of significant resources for use by researchers.
The Library does not receive surplus material which can be given to other libraries. Neither does the Library generally dispose of items in its collections.
The following is an extract from the Library's Collection Development Policy in regards to the discarding of Library material:
DISCARD AND RETENTION OF LIBRARY MATERIAL
1.14 As a legal deposit and research library, the National Library does not generally dispose of items in its collections. Disposal usually only occurs if material has deteriorated to such an extent that it is no longer usable and a surrogate copy has been made, or multiple copies of a publication are held.
