Registration MP5089 No renewal found

Term began: 1954-02-01
Claimant: McGraw-Hill Book Co., inc
Class: MP — published motion picture other than a photoplay (numbering series begun Jan. 1950)
Finding: no renewal entry found for 1981-1983 or in the Copyright Office renewal records 1978-2025
In the public domain since: 1 January 1983 (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 1981 or 1982 volume; volumes searched: 1981, 1982, 1983.

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 MP5089.
