To find information about the collecting institutions which hold the Archival Resources and Published Resources cited in Register entries you can check the list of Trove Partners or the Directory of Archives in Australia.
These two sources provide links to the websites of many hundreds of Australian collecting institutions, including libraries, archives, museums, galleries and historical societies as well as other organisations which hold archives, such as schools, businesses and professional societies.
To find where Published Resources may be held in libraries near you, search Trove using the category Books & Libraries.
