Facebook Original Post: “NERDLOG 182014 – I think it’s interesting to notice how the presence of these words in books, and perhaps their actual presence in the world, move up and down together. When we are truly free we ALL are free.”
Google has this application where you can search the words in title of books from like the 1800s to now-ish. I found it very interesting to choose words and speculate about why certain words appear more or less at certain times.
