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 1966 or 1967 volume; volumes searched: 1966, 1967, 1968.
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 MU9604.
