If anyone is interested in philosophy, religion, or just want to archive it for historical reasons, IIRC sacred-texts.com has a USB version of their entire archive. They sell it, but I’m sure someone could find a work around there, if they were opposed to supporting them* for some reason. It’s a massive collection of philosophical and religious works, and I believe they even have things like constitutions and legal works, as well.

*I know nothing about the people that run it or their ideology
