The Ngram Viewer will let you compare using numerous words or names in one graph. The example that I give up this video is to compare the use of the terms “National Parks,” “National Forests,” and “National Forest Service.” By looking at the Ngram Viewer for those terms I can see that they begin to appear more regularly around 1890, have a lull in the 1940s and 1950s, and after that appear more often again in the 1960s..
Ngram Viewer is based on books indexed in Google Books. That is why below every graph produced by Ngram Viewer you will find a list of books about each of your search terms. Those books are organized by date..
A third 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 supply an excellent way to begin a research study activity for students. Have them get in a few words then analyze the graph to determine peaks and valleys in the frequency of the words use. Then ask to attempt to determine what would have caused those words to be utilized basically often at different durations in history.

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