*There’s not a lot of material on the ancient Indus Valley or related civilizations unfortunately. What does exist often falls short due to limited research and/because of modern/nationalistic politics so I only halfheartedly mention them. It’s problematic (& annoying) that a lot of the material on these topics are by white men. But the alternative is typically even worse: Brahmins, other upper castes and blind apologists. Anyway, Harappa.com, a major website on ancient Indus since 1995, has a list of books worth perusing. Feel free to add further recommendations in the comments!
