@freemo @M0YNG Papers are generally expensive if you aren't at an academic institute and they are also not a great place to learn a new topic. I often find technical information on places like wikipedia either totally inaccessible or so simple its unusable.
Honestly I don't think I've seen anything that comes close to replacing a good textbook. The information is probably all there on the internet, but not nearly as accessible or curated.

I agree, textbooks are generally better. Though with that said there is no shortage of textbooks on piratebay either.
With that said I dont think if you made textbooks free you'd see any fewer flat earthers either as they dont appear to make any effort to learn even the basics, let alone rigorous knowledge like a text book.
