Googles.
Ngram Viewer is a search tool that trainees can use to check out using words and names in books published in between 1800 and 2019. The Ngram Viewer shows users a chart highlighting the very first look of a word or name in literature and the frequency with which that word or name appears in literature given that 1800. The graph is based upon the books and periodicals that are indexed in Google Books.

The Ngram Viewer will let you compare making use of several words or names in one chart. 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 taking a look at the Ngram Viewer for those terms I can see that they begin to appear more often around 1890, have a lull in the 1940s and 1950s, and then appear more regularly again in the 1960s..
Ngram Viewer is based upon books indexed in Google Books. That is why below every chart created by Ngram Viewer you will find a list of books about each of your search terms. Those books are organized by date..
A 3rd part of Ngram Viewer to note is that it works with multiple languages consisting of English, French, Chinese, German, Italian, Russian, Hebrew, and Spanish..

Applications for Education.
As I mentioned in the video above, the Ngram Viewer can supply a great method to begin a research study activity for students. Have them get in a few words then analyze the graph to recognize peaks and valleys in the frequency of the words use. Then ask them to attempt to identify what would have triggered those words to be utilized more or less often at various periods in history.

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