Sleep, My Love

The film was released in 1948 and registered for copyright by Triangle Productions, Inc. (LP1462, 1948-02-18). Under the Copyright Act of 1909, works registered between 1928 and 1963 required a manual renewal filing with the US Copyright Office during the 28th year of the first term to extend protection for a second term. For a 1948 registration, the renewal window was open in 1975 or 1976. A search of the Stanford Copyright Renewal Database and the Library of Congress Catalog of Copyright Entries (CCE) reveals no record of a renewal for this title or registration number. Furthermore, the film is explicitly listed as being in the public domain in 'Film Superlist: Motion Pictures in the U.S. Public Domain (1940-1949)' by David Pierce and Richard Baer. Because the copyright was not renewed, the work entered the public domain in the United States upon the expiration of its initial 28-year term in 1976.
