The Tumblr. Here’s one of the posts:
While doing my comps, I found myself in need of an obscure, unpublished Ph.D. I was still figuring out Proquest and I was trying to figure out a way to order it from the university. As I was doing this, I sent a brief email to a very senior scholar whose work deals with the material in this dissertation and asked if he could recommend the best way to find a copy of it. Instead, he sent the entire dissertation to me by mail – in two packages because it took him a while to photocopy the whole thing (I should also note that I live in a different country, so it would not have been cheap to send). A very kind and unexpected gesture!
