The library offers free high-resolutions downloads of public domain items that can be used without restrictions.

Available items include theatrical programs, drawings, images of original manuscripts, maps, photos, prints, and tourism materials. Materials can be searched by broad topic categories as well (women, African Americans, Jews, military uniforms), which makes this an easy to navigate site to find publicly available digital materials of many different kinds.
