An experiment in open-source education: I've decided to make the reading list for the class on the Soviet collapse that I'm teaching with @leahmfeldman open to the public, along with the commentaries I'm writing for my students.
Unfortunately, social collapse is once again topical, so I hope that these materials help you understand collapse as a phenomenon, past or present. The materials follow below as a thread that will be updated weekly.
Week 2: Economic Collapse/Informal Economies. Also, the week that it was confirmed how amazing these students are, in spite of the current hardships.
