ah nice work! the only issue here is the upside down ones, which i fear takes a bit of human touch...

either way, when they are all done, i'll compile them all together into a pdf and post that so it's easy to read through. like a little book : )

Ah, shucks. Right now I'm having some trouble tracking which ones have already been downloaded... so it re-downloads and re-compiles each time. Can I email you to help figure this out?

The simplest solution would be to just add the filenames of the files that's been already downloaded to a file and it checks the file before downloading anything.

Ah, that's true. Oh well! It's working now. Also: https://news.ycombinator.com/item?id=5575210

Aaaaaand I figured it out again. We're all good!
