By the method, the book that I mentioned in the video is That Wild Country by Mark Kenyon..

The Ngram Viewer will let you compare making use of several words or names in one graph. The example that I give up this video is to compare using the terms “National Parks,” “National Forests,” and “National Forest Service.” By looking at the Ngram Viewer for those terms I can see that they start to appear more frequently around 1890, have a lull in the 1940s and 1950s, and after that appear more often once again in the 1960s..
Ngram Viewer is based on books indexed in Google Books. That is why listed below every graph produced by Ngram Viewer you will discover a list of books about each of your search terms. Those books are organized by date..
A 3rd component of Ngram Viewer to note is that it works with several languages including English, French, Chinese, German, Italian, Russian, Hebrew, and Spanish..

Applications for Education.
As I pointed out in the video above, the Ngram Viewer can provide a great way to start a research study activity for trainees. Have them go into a couple of words then analyze the graph to identify peaks and valleys in the frequency of the words use. Ask them to attempt to determine what would have caused those words to be used more or less regularly at different durations in history.

Googles.

The Ngram Viewer reveals users a graph showing the first appearance of a word or name in literature and the frequency with which that word or name appears in literature given that 1800.
