The record
US Government work The record names a federal body as the creating agency. A work prepared by an officer or employee of the United States Government as part of that person's official duties has no US copyright (17 U.S.C. 105; before 1978, section 8 of the 1909 Act). This says nothing about copyright outside the United States, or about music, stock footage or other material the film may incorporate. Evidence dossier. The finding concerns the US copyright record for the film; it is not clearance for any use, and this page's annotation is machine output.
