Renewal term: older U.S. books
A renewal term is the second period of protection older U.S. works could receive, added to a first term if the renewal was made. As of 2026-09-25.
The U.S. Copyright Office describes older published works as running up to 95 years: a first term of 28 years plus a renewal of 67.
That arithmetic is why the U.S. public-domain line sits at 1931 today and moves forward each January 1.
Project Gutenberg's collection rests on the same law: its books are ones not restricted by U.S. copyright, usually because the period of restriction has ended.
Books whose renewal was never filed can have left copyright earlier, but establishing that means checking records for the individual title.

2Turning the book into episodes
Once the rights in “Renewal term” are settled, SceneMixer describes the adaptation itself like this:
Its character becomes the tone of the episode’s own score, which is planned from the episode’s storyboard — usually one to three pieces — and mixed under the voices.

A producer working in German can make a series whose cast speaks Indonesian: the interface and the working documents follow the interface language, the spoken dialogue follows the project setting.
