This documentary is fascinating to watch. I’ve pasted the trailer here; the movie itself is also available on YouTube. I cried a few times, I was so happy to see the difference this was making for people.
In my historical archaeology class we visited this really cool map archive library that I didn’t know we had. Some insurance company I guess threw out a bunch of their books and my school got ahold of them. They’re cool (but ultimately useless for any of my projects).
