Many items, while not excluded, are the responsibility of individuals other than the American history selector. Material on the native populations of the United States is collected by the Anthropology selector. Area selectors are responsible for works relating to the involvement of the people of their areas with the United States. For example, the African selector acquires material in African American History; the Southeast Asian selector acquires material relating to the Vietnam War and Vietnamese and other ethnic groups in the U.S.; etc. Works relating primarily to American religious, economic, political, legal, literary, or military history are acquired by selectors in each subject area.
