Googles.
Ngram Viewer is a search tool that trainees can utilize to explore the usage of words and names in books published between 1800 and 2019. The Ngram Viewer shows users a chart highlighting the very first appearance of a word or name in literature and the frequency with which that word or name appears in literature considering that 1800. The graph is based on the books and periodicals that are indexed in Google Books.

Applications for Education.
As I mentioned in the video above, the Ngram Viewer can offer an excellent way to start a research study activity for students. Have them enter a couple of words then take a look at the chart to recognize peaks and valleys in the frequency of the words usage. Ask them to try to determine what would have triggered those words to be utilized more or less often at various periods in history.

The Ngram Viewer will let you compare the use of numerous words or names in one graph. The example that I provide in this video is to compare the usage 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 start to appear more frequently around 1890, have a lull in the 1940s and 1950s, and then appear more regularly once again in the 1960s..
Ngram Viewer is based upon 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 component of Ngram Viewer to note is that it works with multiple 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..
