Today, the library collection is located at Melbourne Museum and contains 40,000 titles, which includes around 1,000 titles that are considered to be rare due to one or a combination of factors, including: value; scarcity; aesthetic qualities; historic, scientific or institutional significance; fragility; or age. Collection strengths include natural history in the fields of zoology, geology and palaeontology, scientific expedition reports, society and institutional journal titles, Indigenous cultures of Australia and the Pacific, Australian history, technology, colonial and other exhibition catalogues, museum studies, and Museums Victoria publications.
