Googles.
Ngram Viewer is a search tool that trainees can utilize to explore using words and names in books published in between 1800 and 2019. The Ngram Viewer reveals users a chart illustrating the very first look of a word or name in literature and the frequency with which that word or name appears in literature since 1800. The chart is based upon the books and regulars that are indexed in Google Books.

Ngram Viewer is a search tool that trainees can use to check out the usage of words and names in books released between 1800 and 2019. The Ngram Viewer shows users a graph illustrating the first appearance of a word or name in literature and the frequency with which that word or name appears in literature since 1800. The Ngram Viewer will let you compare the usage of several words or names in one graph.

Applications for Education.
As I mentioned in the video above, the Ngram Viewer can provide a good way to start a research study activity for trainees. Have them get in a couple of words then examine the graph to determine peaks and valleys in the frequency of the words usage. Then ask them to attempt to determine what would have triggered those words to be used basically often at various periods in history.

The Ngram Viewer will let you compare the usage of several words or names in one chart. The example that I give up this video is to compare using 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 start to appear more regularly around 1890, have a lull in the 1940s and 1950s, and then appear more frequently again in the 1960s..
Ngram Viewer is based on books indexed in Google Books. That is why listed below every graph generated by Ngram Viewer you will discover a list of books about each of your search terms. Those books are set up by date..
A 3rd element of Ngram Viewer to note is that it works with numerous languages including 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..
