The Department of Transport Library was one of a number of government libraries incorporated and together formed the Victorian Government Library Service (VGLS) in 2009. The Library holds the library collections of the Victorian Department of Transport, Department of Planning and Community Development and Department of Business and Innovation. The collections of resources from all departments and agencies have now been centralised and provide a whole of government resource for Victorian Public Servants.
The collection covers all subject areas from Legal, Economics, Finance, Environment, Transport, Roads and Infrastructure through to Health and Human Services, Science and Technology and Victorian History. The collection holds in excess of 400,000 items, with a comprehensive journal collection, specialised legal and environmental resources along with an extensive archival collection of Victorian departmental publications.
In addition to material relating to the Department of Transport, Department of Planning and Community Development and Department of Business and Innovation, the Library contains the Peter Watson Duckett Tramways Collection, one of the world's finest collections of tramway material and includes a range of books, magazine, journals and artefacts on trams and light rail from around the world.
