Thanks for the great links! I love free knowledge resources!
Most of these resources I’ll add are well known, but if you didn’t know about them, enjoy!
Librevox has free public domain audio books read by volunteers.
The famous Project Gutenberg has free public domain ebooks.
And of course, the (in)famous Internet Archive has backups of all kinds of digital resources from books to film to video games, including the Wayback Machine for looking at archived versions of websites.
