The National Library's collections range in date from the eleventh century to the present, take in every country in the world and are exceptionally broad in format and subject. They consist of books, pamphlets, periodicals, newspapers, ephemera, maps, manuscripts, private archives, music scores, pictures, microform and digital materials.
A significant proportion of what the Library holds, including some of the rarest and most valuable material, was acquired as collections. Some were built up by individual collectors, families, booksellers and learned societies, often over a long period (formed collections). Other collections have been assembled from various sources by the Library itself in an effort to achieve great strength in particular subject areas (subject collections). Many of the collections have outstanding research value.
The following entries are for the most significant of these collections. The entries give details about the individuals, families or organisations that assembled the collections, describe the size, scope and strengths of each collection, and summarise how they have been acquired, organised, catalogued or listed by the Library. While the majority of the collections described consist largely of Australian materials, there are also entries for significant Asian, European and North American collections. These descriptions are intended to complement the Library's catalogue and other finding-aids.
Between 1974 and 1982 the Library published the Guide to the collections, edited by C.A. Burmester. A number of the collections recorded in that publication have been updated and are included in the following selection.
About 600 books and 66 serials mainly relating to entomology and the natural sciences. The strength is works on British entomology but also includes Europe, North and South America. About one-third were published in the 18th and 19th centuries
535 pamphlets on socialism and related subjects published in the Netherlands, Germany, Austria, Czechoslovakia, the USSR, France and Britain from 1875-1950
