1. Introduction The National Library of Australia has provided interlibrary loan and document delivery (ILL/DD) services since its inception in 1960. These services are provided to libraries and organisations, as well as to individuals, both in Australia and overseas. Copies and loans are generally supplied from the Library’s own collections. The Library also offers mediated services to obtain copies and loans from other institutions on behalf of requesters. All services are provided on a cost-recovery basis.
