All material created by and made available on this website by GVP is governed by the Smithsonian Terms of Use. The Smithsonian invites visitors to use its online content for personal, educational and other non-commercial purposes.

The Smithsonian is the owner of the compilation of content that is posted on the SI Websites, which consists of text, images, audio, video, databases, design, codes and software ("Content"). However, the Smithsonian does not necessarily own each component of the compilation. The Content that the Smithsonian makes available on the SI Websites may be owned by the Smithsonian, owned by others and used with their permission (such as user-generated content), or used in accordance with applicable law. Some Content is in the public domain and some Content is protected by third party rights, such as copyright, trademark, rights of publicity, privacy, and contractual restrictions.

Smithsonian Content is identified as having "no known copyright restrictions" when the Smithsonian is unaware of any copyright restrictions on its use. This may mean that: (1) a copyright existed at one time but was not renewed, or the copyright may have expired, or the owner may have intentionally placed the Content into the public domain; or (2) the Content was never eligible for copyright protection because it was created by an employee of the United States as part of his or her official duties, or (3) there are no copyright markings or other indications on the Content to indicate that it was copyrighted or otherwise restricted; or (4) Smithsonian records do not indicate any evidence of copyright restrictions. These facts do not necessarily mean that the Content is in the public domain, but rather indicate that no evidence has been found to show that copyright restrictions apply.

The Smithsonian welcomes you to make fair use of the Content as defined by copyright law. Information on United States copyright fair use law is available from the United States Copyright Office. Please note that you are responsible for determining whether your use is fair and for responding to any claims that may arise from your use.
