Well I have mostly read some bougie ancient history of Vietnam but I will post some screenshots from more based books which aren't specifically about Vietnam but have useful sections about Vietnamese history (also Laos Cambodia and China) with Libgen links on /c/history@lemmy.ml or here and ping you when I get home

I am pretty lightweight on ancient history everywhere and I've been trying to remedy it. While I often diverge from their opinions on modern times post-1990, world systems writers are very good about this. There are a few journals here and there which actually post world systems papers too
