On a related note, I think Anna's archive might be the last remaining bastion for books after library genesis got shut down recently. Is anyone aware of other alternatives?
It's called Nexus (or LibrarySTC?) https://libstc.nexus/
It's very fast and efficient. I've never seen a bot get taken down either.
I still mainly use LibGen for books. Got me through college and probably saved me well over $2k on textbooks throughout my courses
