Okay, a couple of hours later…thanks for the hint as that's fucking dark magic ;) and I now have access to the entire New Yorker again after around 15 years :)

I'll have a more proper github repo at some point, but there are bugs I was working through. Some issues are bloated up ridiculously... a 9mb djvu file shouldn't become a 110mb pdf. Most issues will work well though. Hope it helps.
