National and State Libraries Australia

National and State Libraries Australia (NSLA), formerly National and State Libraries Australasia, is the peak body that represents the national, state and territory libraries of Australia. The libraries collaborate on and support working groups addressing issues including: copyright issues, archival collections, collection development, marketing, collecting and preserving digital content, collections and services focusing on Indigenous Australians, and other issues relating to the collection, storage and dissemination of the various types of resources held by member institutions. It also compiles annual statistics on public library activities and usage throughout Australia, and publishes statistics on the services of its own collaborating libraries. Precursors to the organisation include the State Librarians Council, the State Libraries Council and Council of Australian State Libraries (CASL).

NLSA also collaborates with partner organisations such as the Australian Research Council on research and development projects. One of its latest major completed projects is the development of the National edeposit service (NED), "an online service for the deposit, archiving, management, discovery and delivery of published electronic material across Australia", which was formally launched in August 2019.
