From the post:
JSTOR have just announced the JSTOR Labs Text Analyzer, a clever tool–still in Beta–that will analyze any document you upload (or text that you copy and paste) and find suggested matches in the JSTOR archives. It’s an interesting proposition–if you click that link on a phone, you can even take a picture of text and the Analyzer will process that. You can find out more about how it works at this link, but I thought it would be fun to run it through a paper I published a while back.
