THANK YOU. I am confused tho, you gave at least one example on Archive.org but are discussing Google. Does google have control of whats on Archive.org, or are you talking about youtube that google owns, or another google platform for audiobooks?
Here's The Colored Patriots in a playlist form on Google's YouTube.

The reason I'm discussing Google is because this one audiobook I produced has been put up on YouTube from Librivox by at least four or five other people/organizations outside of myself. Which means, Google can never get rid of it.
That's the flip side of public domain work, I get the deep benefit of mass proliferation. It's practically immortal.
