The photographs were owned originally by either the S. D. Warren Company or the Warren Family and any copyright in the photographs has long since expired. Clarification of ownership and copyright was officially given to the Warren Memorial Library on October 18, 1997 by Briana K. O'Regan, Manager, Intellectual Property of Sappi/Warren. The photographs were brought over to the Warren Memorial Library between 1958 to 1966 by mill employees whose spouses worked at the library. Older prints are identified with mill photographers.
