In the United States, each state supports a state library supporting the work of the legislature and other state employees. The library typically maintains a collection of state publications, works by local authors, and local publications, such as newsletters. State libraries serve as the State Library Administrative Agencies, the official agencies charged by law with the extension and development of library services under the Grants to States program of the Institute of Museum and Library Services (IMLS). They are located in each of the 50 states and the District of Columbia, U.S. Territories (Guam, American Samoa, the Commonwealth of Puerto Rico, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands), and the Freely Associated States (Federated States of Micronesia, Republic of Palau, and the Republic of the Marshall Islands).
