The majority of images in "Beautiful Birds: Masterpieces from the Hill Ornithology Collection" are believed to be in the public domain in the United States by virtue of their creation date (pre-1923). This collection was digitized by Cornell University Library in collaboration with the Cornell Lab of Ornithology in 1999 from books and prints held in their collections, curated by Jeanne A. White. Funding was provided through an endowment established by Kenneth E. and Dorothy V. Hill. Cornell is providing access to the materials as a digital aggregate under an assertion of fair use for non-commercial educational use.
