While abroad we couldn't find a New York Times anywhere in order to grab the crossword. After a few months we finally caved in to the $7 a month subscription for access to the NYTimes Crossword archive of over 5,000 puzzles. It is ridiculous that this subscription is separate of their other digital subscription pricing, but unfortunately they hold the keys to the puzzles.
Now that we are back, I don't need this subscription anymore, but that didn't hold me back from writing a script that will download the whole archive for my personal use. Get the code on github here
Also if you haven't yet seen the documentary Wordplay about the NYTimes puzzle and the annual crossword convention, I highly recommend it. It stars Will Shortz and a bunch of famous crossword-ers like Jon Stewart, Ken Burns and Bill Clinton.
