WHAT IS TROVE? • Trove is a discovery experience focused on Australia

and Australians. It supplements what search engines provide. • Launched in 2009

• If you are researching in the fields of the social sciences, literature, local or family history, or need inspiration for your school assignment, then this is the tool for you.

• Example • if researching images relating to Edmund Barton,

Australia’s first Prime Minister, results will include descriptions such as people, book, manuscript, map and newspaper articles where the images appear.

• A researcher searching for information on Nellie Melba will be presented with a range of results including biographies, pictures, music, newspapers, books etc.

THE DRIVERS FOR DEVELOPING TROVE Trove was designed to:

• provide a single point of access to the resources of the deep web

• facilitate access to a significantly greater range of resources from major sources, including selected digitized material freely available online

• support searching of, and access to, full-text content

• enhance ease of discovery by providing improved relevance ranking, refinement by facets, grouping of all editions of the same book (this is known as FRBR-like grouping) and exploitation of thesauri

• engage with communities and individuals through annotation services

• ensure that relevant information is not missed in a search by reducing the need to search material-specific discovery services separately

• provide a platform for niche services to query a vast resource of Australian metadata and adapt if for their own needs.
