omg so I forgot that I ever made this thread in my brief attempt to get back into PS in 2015 and started screenshotting all the books in Jayose's library for my own reference upon return in 2017. Aaaand I forgot the blog that Cairn linked me earlier in the thread. So I spent hours for nothing as it turns out.
I didn't even finish half of the library though so there's that. I might, on a personal level, screenshot-archive knowledge seeker books and the books in the other three libraries for myself unless that's also considered essential?
Nevertheless, good to see this revisited.
