Ok wrt recent asks about cultural worldbuilding, here's a drive folder with a very large collection of mostly nonfiction (~142 books right now), kept to a Very loose theme of history and social sciences, in pdf or epub format.
History (largely pre-modern period but not entirely), material culture, trade and economics, agriculture, magic and religion, folktales, (epic) poetry, natural history, ethnobotany, ethnobiology, kinship, animal social history, etc. Wildly variable mix of books for general readership and academic audiences.
This is assembled through a combination of PDFs I'd already accumulated, my library checkout history, reading list, and things I found in the process of making this. I have not read every single thing in here (some I’ve only read parts of, some I haven’t touched) and can’t attest to the quality of every book, this is just an assemblage of potentially worthwhile reading.
