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 making 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 start to appear more often around 1890, have a lull in the 1940s and 1950s, and after that appear more regularly again in the 1960s..
Ngram Viewer is based on books indexed in Google Books. That is why below every graph created by Ngram Viewer you will discover a list of books about each of your search terms. Those books are organized by date..
A third element of Ngram Viewer to note is that it works with several languages consisting of English, French, Chinese, German, Italian, Russian, Hebrew, and Spanish..

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