Hey anon. I made this chart. I'm thinking I should update it. There's a lot of books that anons have recommended me that I still haven't added. I feel bad about that. There's also more stuff I should add to the medieval section.
Not sure what I'd add for a 21st century section. It gets more difficult to determine what should be 'canonical' by the standards of /lit/, partly because there's like a trillion gay slop books published every millisecond now. I did have one on there for a little while (pic related)
In any case, it would have to be stuff that is either particularly good/literary or appeals in some way to the unique sensibilities of /lit/ users
