Yes, it is only for books that allowed to be published freely.

https://www.gutenberg.org/wiki/Gutenberg:Copyright_How-To

Also, archive.org has large collection of old books too. And multiple libraries in the world.

Actually, I found that finding copyrighted book in English is relatively hard task. For Russian there is flibusta, it has almost any fiction book, but there is no such big site for other languages. Maybe only libgen and that IRC channel that I forgot.
