As a result of a crowdfunding campaign a couple of years ago, I printed 21k copies of HPMOR. 11k of those were sent to the crowdfunding participants. I'm looking for ideas for how to use the ones that are left with the most impact. Over the last few weeks, I've sent 400 copies to winners of IMO, IOI, and other international and Russian olympiads in math, computer science, biology, etc. (and also bought and sent copies of Human Compatible in Russian to about 250 of them who requested it as well).
