I’ll start by plugging Harvard’s free courses catalog as well as Udemy
Edit: Gonna add 2 more I remembered-
Blender - I wish I had more time to learn it, but I did start the infamous “Donut Tutorial” once!
Watch Cartoons Online - Lots of good older stuff!
Making sure to keep it legal, right?
Let’s stick with Project Gutenberg - Public domain ebooks and other media, spanning centuries. They’re incredibly important for keeping our literary past alive.
I might have more later.
I got a cooking book from the 1800s there, sadly the pricing is a bit off, I don’t think that recipe is 19 pence anymore.
