Its library, in addition to housing an extensive collection on Lincoln, also houses the collection of the Illinois State Historical Library, founded by the state in 1889. The library and museum is located in the state capital of Springfield, Illinois, and is overseen as an agency of state government. It is not affiliated with the U.S. National Archives and its system of libraries.
