The citation graph is one of humankind's most important intellectual achievements

Thanks for the info. I agree this would be better. If you parsed it from sci-hub, you’d pretty much have to only make it available the same way as sci-hub.

A simple parser would not be enough. You’d have to have some croudsourcing code, like asking the person using the graph to classify marginal cases for their graph, and adding the results to the database.
