Class
MP — published motion picture other than a photoplay (numbering series begun Jan. 1950)
Finding
no renewal entry found for 1980-1982 or in the Copyright Office renewal records 1978-2025
In the public domain since
1 January 1982 (end of the 28th year, no renewal)

A renewal would have appeared in the Copyright Office's renewal registrations 27 to 29 years after the term began. Those volumes are loaded and no matching renewal was found. A work published 1931–1963 that was not renewed entered the public domain at the end of its 28th year.

A renewal had to be filed in the 28th year and would be listed in the 1980 or 1981 volume; volumes searched: 1980, 1981, 1982.

The renewal sections are OCR text of printed volumes; a damaged record can hide a renewal. Before relying on this, search the linked volumes yourself for the title and for number MP3592.
