Registration MP3706 No renewal found

Term began: 1948-12-17
Claimant: David A. Smart
Class: MP — published motion picture other than a photoplay (numbering series begun 1946)
Finding: no renewal entry found for 1975-1977 in the CCE motion-picture renewal sections
In the public domain since: 1 January 1977 (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 1975 or 1976 volume; volumes searched: 1975, 1976, 1977.

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 MP3706.
