Trove is a website run by the National Library of Australia. They host digitised scans of old newspapers, magazines, maps, books, photos, etc. as well as people/organistation bios and librarian-submitted release metadata for video and audio releases (including where to loan a release out). The data quality/comprehensiveness is generally lower than our own.
