Research is
necessary not only to the preparation of interesting material to serve
as a basis of the naturalist and historical service, but it also is
fundamental to the actual protection of the natural features of the
parks, as enjoined in the acts establishing the parks and in the act of
August 25, 1916, creating the National Park Service.

While NPS-produced publications are normally considered to be in the
public domain, many of the reports contain illustrations that are copies
